ABSTRACT:
Novel oxymethylene graft polymers are obtained by grafting a functional compound (i.e., a polymer or compound having one or two hydroxyl, carboxyl, or amine functional groups) onto an oxymethylene backbone having pendant hydroxyl groups which serve as reactive sites for the graft reaction with diisocyanate coupling agents.
