  • Patent number: 6991745
    Abstract: Methods of applying a polymer coating to a substrate are disclosed. By disrupting a bank of polymer precursor, a smooth coating of fast setting polymer can be applied to a substrate. Apparatus for applying a polymer coating is also disclosed. In one embodiment, an oscillating dispenser is used to apply polymer precursor onto a dispersive surface. The polymer precursor flows down the surface and is transferred to a moving web. Flowing solvent downwardly through the dispenser can provide efficient cleaning without the need for disassembly or production delays.

  • Patent number: 6979493
    Abstract: A polyurethane resin having a total concentration of the urethane group and the urea group of not less than 15% by weight is prepared by reacting a diisocyanate component (e.g., an aromatic diisocyanate) with a diol component (e.g., a C2–8alkylene glycol). The repeating unit of the polyurethane resin may contain a constitutive unit of an aromatic or alicyclic compound. The polyurethane resin may be shaped into a film for use as a gas barrier film. The film may be a gas barrier composite film composed of a base film layer and a resin layer at least comprising the polyurethane resin. The present invention provides a polyurethane resin excellent in gas barrier properties against water vapor, oxygen, aromatics, and others, and a film containing the same.

    Abstract: A mixture is provided comprising (a) at least one of an elastomeric thermoplastic, a non-elastomeric thermoplastic, an elastomeric thermoset and mixtures thereof, excluding polydiorganosiloxane fluids and (b) a polymer having soft polydiorganosiloxane units, hard polyisocyanate residue units, optionally, soft and/or hard organic polyamine residue units and terminal groups. The hard polyisocyanate residue and the hard polyamine residue comprise less than 50% by weight of the polydiorganosiloxane urea containing component. The polyisocyanate residue is the polyisocyanate minus the —NCO groups and the polyamine residue is the polyamine minus the —NH2 groups. The polyisocyanate residue is connected to the polyamine residue by urea linkages. The terminal groups are non-functional groups or functional groups. The polydiorganosiloxane urea containing component may be reactive under free-radical or moisture curing conditions.

  • Patent number: 6841646
    Abstract: A poly(urea-ureathane) based on polydimethyl siloxane is prepared by reacting an amino-terminated polydimethyl siloxane with polyisocyanate to form a prepolymer of poly(urea-urethane), and reacting the prepolymer and a chain extender in the presence of a catalyst. The resulting poly(urea-urethane) contains about 5-65 wt % of hard segments, and has a surface resistance of about 10-150 M? at high relative humidity, so that it can be used in anti-static electricity and electrostatic discharge shielding.

  • Patent number: 6841255
    Abstract: The present invention includes a co-polymer film which can be applied over a surface of an article to form a continuous surface that is more biocompatible and has a smoother surface morphology than an untreated article. In general the co-polymer film of the invention can be formed by providing a hydrophobic polymer block, such as polydimethylsiloxane (PDMS) with functional —OH end groups and reacting the —OH ends with a conventional monomer or prepolymer of a film-forming polymer capable of reacting with —OH groups. Such reactions are exemplified, using as reactive PDMS a triblock copolymer of the polylactone-polysiloxane-polylactone (PL-PDMS-PL) type, or silicone polyesters. The —OH groups of the polylactone blocks can react with any of a variety of isocyanates in a suitable solvent to form a polymer having PDMS incorporated with its structure.

  • Patent number: 6838541
    Abstract: Siloxane-based polyamide elastomers can be prepared by heating a reaction mixture containing an olefinic acid and an organic amine to form an organic amide, and reacting the organic amide with a hydride functional polyorganosiloxane in the presence of a hydrosilylation catalyst to form the siloxane-based polyamide elastomer. The hydride functional polyorganosiloxane contains at least one pendant hydrogen. The elastomers are useful additives in personal care products and can be applied to the hair, the skin, or the underarm. They can also be used to modify thermoplastic nylons, and for treating woven and non-woven textiles, such as air bags, carpeting, and apparel.
