    摘要: A polyelectrolyte complex composition capable of viscosifying or thickening an aqueous high salt-containing system comprises a mixture of at least one anionic polymer and at least one cationic polymer in an inorganic salt-containing aqueous medium. The anionic polymer and cationic polymer can each be linear and water-soluble, crosslinked and water-soluble, or crosslinked and water-insoluble or swellable.

    摘要: Aqueous-borne coating compositions containing:(A) an acetoacetylated polymer; and(B) a polyacrylate having at least two (meth)acrylate end groups,have long pot lives and may be cured by the evaporation of water in the presence of a basic catalyst. Acrylic copolymers having pendent urethane side groups which are terminated with (meth)acrylate groups are water-dispersible and may be cured with polyfunctional crosslinking agents or by free radical initiators to afford coatings having excellent properties. Incorporation of a crosslinking component containing epoxy groups improves the coating properties.
