ABSTRACT:
Graft copolymers of vinyl monomers and unsaturated polyols are described. These copolymers are prepared by the polymerization of an ethylenically unsaturated monomer, or a mixture of such monomers, in a polyol comprising an alkenyl aryl polyol. The alkenyl aryl constituents render the polyols compatible for graft copolymerization with the vinyl monomers. The graft copolymers are shown in polyurethane formulations.
