ABSTRACT:
This invention relates to water-compatible crosslinkable associative polymers prepared from (1) hydrophilic hydroxyl compounds having a number average molecular weight greater than about 3000 and less than about 20,000, (2) hydrophobic polyisocyanates and (3) hydroxyl-functional vinyl compounds. The polymers can be polymerized by radiation, or by free radical, redox, or thermal initiation, in water or as a film dried from water (or other solvents) on a substrate.
