Summary

Polyurethane-poly(methyl methacrylate) graft copolymers of well-defined structure and composition were synthesized by macromonomer method. Dihydroxyl-terminated macromonomer was prepared by radical polymerization of methyl methacrylate in the presence of α-thioglycerol as a chain transfer agent. This dihydroxyl-terminated macromonomer and 1,4-butanediol were added to diisocyanate (hexamethylene diisocyanate or toluene-2,4-diisocyanate) catalyzed by di-n-butyltin dilaurate to produce tailor-made graft copolymers.
