Abstract
Vinyl urethane composite polymers are prepared by reacting a vinyl monomer, a polyahl, and a polyisocyanate in the presence of a vinyl-terminated urethane oligomer in specified proportions. The oligomer provides significantly improved impact strength and elongation to the composite. The composite is useful in preparing molded materials such as furniture and machine components.
