<p>Low molecular weight isocyanate-functional acrylic polymers are provided, which contain at least 10% by weight of copolymerized isocyanatoalkyl (meth)acrylate, are substantially free of toxic monomeric isocyantes, and have the following general structure: where R is alkyl or aryl, R1 is hydrogen or methyl; X is COO-A-NCO or a mixture of COO-A-NCO and at least one of phenyl, COOR2, , Cl, H; where A is an alkylene group having 2-6 carbon atoms, and R2 is an alkyl group having 1-18 carbon atoms; and n is 2-400. These polymers can be crosslinked and are useful in a variety of applications such as finishes, pigment surface treatments and dispersants, and theology control agents.</p> |
