LIQUID DISPERSION POLYMER THICKENERS FOR AQUEOUS SYSTEMS
摘要
<p>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.</p>
