Graft copolymers from unsaturated monomers and peroxy di-ester polyols and polyurethanes prepared therefrom

摘要

Graft copolymers are prepared by the polymerization of an ethylenically unsaturated monomer, or a mixture of such monomers, in the presence of a peroxy di-ester polyol. Presence of the peroxy group in the polyol reactant itself serves as a free radical initiator site for the graft copolymerization reaction. The copolymers formed are utilized in the formulation of polyurethane compositions.
