Methods of attaching/grafting linear alpha-olefins onto PE, polyester elastomers, fluoros and other

linear alpha-olefins, PE, polyester elastomers, fluoros
- Resultado deseado
  
  Our client needs to functionalize polymers by grafting a linear aliphatic olefin to the polymer backbone. The polymers we're working with include harder-to-functionalize materials -- in particular polyethylene, fluoropolymers, and thermoplastic polyester elastomers (such as DuPont Hytrel®).

  Detalles de la demanda :
  
  BACKGROUND
  
  Our polymer applications often require high temperature resistance and high materials performance. Often, our polymers must perform at 150 degrees C, or even up to 280 C as in the case of polyethylenes.
  
  We are particularly interested in grafting an aliphatic alpha-olefin to a thermoplastic polyester elastomer. The terminal double bond functional group must be retained in the final polymer.
  
  CONSTRAINTS
  
  A dendromeric olefin would prohibit other processing we need to perform on the material.
  
  General high-temperature stability.
  
  Prefer no other functional group within six carbons of the olefin, but this is not a requirement.
  
  Prefer solutions that can generalize across polymers, but this also is not a requirement.
  
  POSSIBLE SOLUTION AREAS
  
  Hydrogen bonding
  
  Olefin sidechains
  
  Biology, wound-healing, blood/fibrin reactions
  
  We are looking for a method to functionalize/add aliphatic terminal olefins to polymers. Ideally this would be a secondary process that could be applied to a range of polymers. We are looking for generally, but not exclusively, high performance polymers.
  
  Field Of Use and Intended Application
  These products will be used in the area of connectors, housings, wire, cable and tubing.
  
  Desired Outcome
  Although we may wish to manufacture small batches, ideally, we'd be able to purchase the olefin-grafted polymer from a secondary company that makes the material for us.
  
  The olefin containing polymer will be compounded into a formulation that will be made into components such as connectors, housings and other moldable parts. This technology will allow for the formation of a more durable polymer in a secondary processing step, e.g. higher use temperature, abrasion resistance, increased stiffness.
  
  Previously Attempted Solutions
  Hydrogen bonding: difficult to make, unstable, not durable, and it is sheer-sensitive.

  Many consumer, biopharmaceutical, food, agricultural products consist of complex liquid formulations containing proteins such as various enzymes, (e.g, lipase, protease, amalyase, lactase, catalase etc) in combination with polymers, surfactants, sequestrants etc. Engineering the stability of these proteins in such a complex formulation is highly challenging as it not only depends upon the interaction of these proteins with other formulation components but is also linked to formulation conditions such as ionic strength, pH etc. When combinations of different proteins are present, this makes the problem even more challenging. We are seeking technologies that will allow the stability of proteins to be enhanced and will also allow a drastic reduction or elimination of interactions with other proteins and formulation components.
  
  All encapsulation based technologies must protect in formulation but have a mechanism to trigger release of its payload when needed. Triggers of interest are dilution, formulation solubility, ionic strength, surfactant concentration, enzymes. Encapsulation technologies should be fast triggered and they must in addition demonstrate full segregation of the enzyme/protein until the initiation of the trigger (i.e. no leakage of active.)

  We seek a novel low cost, food-grade material suitable for applications including as a bouquet garni (dried herbs) sachet used in cooking. The material should have a high degree of optical clarity so that the quality of the ingredients within can be clearly seen.
  
  Potential solutions could include:-
  New bio-based materials requiring further processing
  Processes (e.g. perforation) to convert existing substrates
  Fully formed materials requiring no processing
  Materials with changeable properties (e.g. permeable under certain conditions)
  
  We are interested in reviewing all opportunities, from early stage technology to commercially available solutions, but end material should meet the following characteristics (we are interested to look at solutions that only partly fit the characteristics if they can be developed further):-
  - High degree of visual transparency / opaqueness
  - Perforations (holes / slits, etc) to be 50-200 micron diameter
  - Low cost – price should be less than €50 / kilo

  DESIRED OUTCOME: An additive package that will prolong the stability in the can, without negatively influence the reactivity when applied and exposed to UV light.
  
  BACKGROUND: UV curable coatings and inks have grown very fast during the last 15-20 years due to it is an environmental friendly and cost effective technology. However, it has some inherent drawbacks e.g., not 100% conversion and shrinkage upon curing as it is made from acrylate functional monomers and oligomers. This will give poorer adhesion to many substrates. A UV curable thiol-ene based system can overcome these problems and has excellent mechanical properties, why it is of high interest to get a well working system. The system is normally made from a thiol or mixture of thiols for example trimethylolpropane-tri-mercaptopropionate and an ene or mixture of ene compounds, for example acrylate or allyl ether functional oligomers. The composition contains also a UV initiator and potential flow and surface active additives, fillers etc. The drawbacks with thiol-ene have been smell and poor pot-life, that is poor stability in the can, due to premature reaction. Today the smell is considerable lower and the main issue to solve is the stability.
  
  EHS REQUIREMENTS: The solution shall not include any substance that is toxic, carcinogenic, mutagenic or repro-toxic. REACH registered compounds are preferred.
  
  COMMERCIAL REQUIREMENTS: The solution must be an economical solution. Leer más

Printed electronics technologies that enable thicker, higher-viscosity circuitry, good adhesion, etc

printing electronics technology
- Resultado deseado
  
  This organization seeks printing technology to produce higher-current miniature circuitry.

  BACKGROUND
  
  Applying print technologies such as inkjet to circuitry offers rapid prototyping and potentially inexpensive production opportunities for many electronic devices that range from RFID tags, through intelligent cables, to flexible displays and touch screens.
  
  Currently, this company prints their circuitry using a relatively low-viscosity ink that incorporates silver nanoparticles. They print in a single layer -- with some adhesion difficulties, depending on substrate -- and then electroplate on top of that in order to provide a trace that can handle higher currents. They are aware of several printing technologies that may be adapted to the process, such as variations on inkjet, metal-jet, gravure, screen, stencil, and laser transfer printing, each of which has advantages and drawbacks.
  
  They are looking for several possible technological answers:
  
  o An alternate ink material that may have lower viscosity but that can produce the trace thickness capable of handling sufficient current.
  
  o Higher silver loadings (on the order of 40-60%).
  
  o An inexpensive seed ink that could be electroplated (or used with electroless deposit) and then electroplated afterwards, but where the seed is much less expensive than the silver currently used. Finished thickness needs to be in the range of 50-70 microns.
  
  Key characteristics include good adhesion to a variety of substrates, including dielectrics and polymers including flexible substrates, as well as the usual properties of good ink: jettable, small drop volumes, and excellent control over surface tension and viscosity.
  
  CONSTRAINTS
  
  o The ability to print thicker traces to handle higher currents.
  
  o The ability to print multiple layers. Currently, later passes disturb traces laid down by earlier passes.
  
  o Higher silver loadings for the ink, or a different seed technology that is less expensive than silver.
  
  o Excellent control over surface tension and viscosity.

We are open to new additives that enhance any of a long list of properties, or that can enhance the performance of additives already in use.

  Any additive changes the balance of properties for a given plastic. Talc, wollastonite, and glass fibers are the most usual conventional additives. Typically, talc can comprise 10-30% of a polypropylene by weight. While talc produces a stiffer plastic, the resulting composite is relatively dense. Glass fiber can typically provide the same stiffness as talc at lower use levels. While this provides a less dense composite, it presents other challenges -- such as undesirable surface defects.
  
  Our client's focus is on finding new ingredients, modifiers, or agents that improve the balance of properties of a thermoplastic (in particular, a polyolefin) over what is currently used today. The list of properties of interest includes:
  
  o Lighter weight
  o Higher modulus
  o Increase tensile strength
  o Improve impact resistance
  o Improve heat resistance
  o Decrease density (while maintaining the same or greater strength)
  o Minimize shrinkage
  o Improve surface finish, feel, optical appearance, and similar aesthetics
  o Improve scratch resistance and surface hardness
  o Improve stiffness
  o Minimize or eliminate abrasiveness (causes problems during extrusion)
  
  Ideally, your proposed additive would provide new properties in plastics or improvements over anything currently available; or, your additive would maintain current-equivalent properties but at a greatly reduced weight or much lower cost. For example, we would be interested in a technology that would enable a lower-cost polymer resin to replace a higher-cost resin without sacrificing quality, or a resin that would provide equivalent performance to a high-cost resin, but at a lesser quantity.
  
  Early-stage technologies are acceptable, but it is preferred that you have reduced the technology to practice at least at the lab scale.
  
  CONSTRAINTS
  
  Safety is important to us. Any new ingredient should not create safety hazards when inhaled during mixing or cause harm during incineration or processing.
  
  Your additive must work with an extruder (or possibly a compounder). An additive that is too abrasive -- over 6.5 on the Mohs hardness scale -- may be harder than the steel in an extruder. We may make an exception for a true nano-scale additive.
  
  No restriction between organic or inorganic additives.
  
  We are NOT currently interested in new polymers (unless the polymer is added to polyolefins), new processes, or new machines.
  
  POSSIBLE SOLUTION AREAS
  
  Materials science in organics and inorganics.
  
  Solutions from paper/packaging industry, metal, ceramics, thermoset resins.
  
  Additives from other industries that might be dispersable into polyolefins.
  
  Field Of Use and Intended Application
  Durable goods, automotive parts, construction, decking, siding.
  
  Desired Outcome
  Ideally, you will provide one or more new additives that can provide enhanced or additional properties not currently available for polyolefins or polyethylenes.
  
  Previously Attempted Solutions
  We have tried, and remain interested in, new methods and approaches to more traditional materials such as clays, talcs, glass fibers, etc. Technology must bring new value to enhance current offerings such as novel dispersion technologies.

  The effect has been noted at various conditions. The temperature of the water can be anywhere from 5'C to 95'C. The ration of textile to water is from 1:10 to 1:3. The pH of the water can be from 6 to 11. This is not to say these are limits as more extreme conditions may also exhibit the effect. PQs are known to provide benefits such as nice 'feel' at low cost in many personal care products however when the personal care product is directly applied to fibers and fabrics, they can cause staining. If any colors come into contact with the PQs in an aqueous environment, the PQs will effectively 'suck in' the color bodies. The color bodies can be from grass stains, inorganic particulate soils (clay) or even fugitive dyes from other fabrics. The adhering is most acute with cotton fibers, but solutions that prevent adhering on any fibers are of interest.
  The current blocking approach uses sulfonated styrene malaic anhydride (SSMA) in high concentration to inhibit color bodies from contacting and adhering to the PQ.
  
  Background
  We believe that the cationic substituents are a cause of the problem. Nonionic based detergents are most affected by this phenomenon while detergents with high anionic surfactant levels exhibit similar behavior, but to a much lesser degree; Note, however, that [PQ7], which is common in many hand soaps appears to be unaffected by surfactant type.. Neutralizing the polyquat positive charges seems to help in inhibiting the reaction.
  
  Possible Solutions:
  
  - Remove the poly quats from the fibers
  - Provide a cheaper alternative to SSMA to neutralize or block color bodies from contacting/adhering. This could be accomplished either by targeting the PQs directly, or by generically infusing the whole aqueous environment with the blocker/inhibitor (as is currently done)
  - Reduce the amount of SSMA required to effectively block the adhering (current concentrations for efficacy in a nonionic surfactant based detergent are 60 ppm to the aqueous system )
  - Target the stain directly (have to get there before the color gets there) OR generic solution (much higher concentrations required).
  
  Constraints:
  
  - Needs to be human-safe (GRAS)
  - Preferably biodegradable
  - Definitely needs to meet Design for the Environment (EPA) criteria
  
  Desired Outcome
  Cheaper, more sustainable method for preventing colors from adhering to PQs during washing of the underlying fibers/fabrics.
  
  Previously Attempted Solutions
  Using poly sulfonated styrene malaic anhydride (SSMA) – inhibits the color bodies from contacting and adhering to the PQ.
  Attemped to use polycarboxylates, acrylates and co-polymers. Solvents - mineral spirits, polar, non-polar, even chlorinated. None of these approaches worked.
