Abstract:
Disclosed is an aqueous latex emulsion coating composition comprising a liquid dispersion polymer, said liquid dispersion polymer comprising a hydrophilic nonionic or anionic homopolymer or copolymer dispersed in a hydrophobic liquid carrier and containing an oil-in-water activator surfactant and wherein the liquid dispersion polymer is in the form of microparticles. The hydrophilic homopolymers or copolymers comprise for example monomer units derived from acrylic acid or acrylic acid salts. Also disclosed is an associative liquid dispersion polymer, said liquid dispersion polymer comprising a hydrophilic nonionic or anionic copolymer dispersed in a hydrophobic liquid carrier and containing an oil-in-water activator surfactant and wherein the liquid dispersion polymer is in the form of microparticles, and wherein the copolymer contains a minor amount of associative monomer units derived from ethylenically unsaturated monomers selected from the group consisting of the associative monomers. The associative liquid dispersion polymers are useful as thickeners for aqueous emulsion systems.

The aqueous polymer dispersion is useful for preparing coatings having improved adhesion to substrates.
Abstract:
The present invention provides novel compositions prepared from a first oligomer containing reactive functional groups capable of reaction at effective rates (at normal processing temperatures) with a co-reactive second component possessing functionality that is complementary to that of the first oligomer. The compositions may be used as coatings, including hard surface coatings, clear coatings, powder coatings and pattern coatings; as adhesives, including pressure sensitive adhesives and not melt adhesives; as sealants; as optical coatings; as blown microfibers (BMF); as high refractive index optical materials; as barrier films; in microreplication; as low adhesion backsizes, (LABs) and release coatings.

Abstract:
A polymer having an antibacterial activity and heat-treatability or thermoformability is produced by melt kneading a mixture of a heat-fusible thermoplastic copolymer having repeating units derived from an ethylenically unsaturated carboxylic acid or anhydride thereof with silver oxide. When applied to the inside of a packaging material, the polymer can exhibit an antibacterial effect upon the contents without detriment to the flavor retentivity thereof.
