Abstract

Isocyanatoethyl methacrylate/acrylate (or other vinyl monomer) copolymers of controlled low molecular weight are produced by copolymerizing the monomers with initiators, usually peroxides, at temperatures above 120.degree. C. The copolymers are particularly useful as curing agents for urethane coating compositions.
