Abstract
Graft copolymers are prepared by the copolymerization of an ethylenically unsaturated monomer, or a mixture of such monomers, with a polyurethane oligomer in a polyol. The polyurethane oligomer is the reaction product of an isocyanate-terminated prepolymer with an isocyanate reactive group-containing unsaturated monomer. The graft copolymers are useful in polyurethane formulations.
