Abstract
Abstract Polyahls comprising (1) a backbone having a random arrangement of (a) a plurality of alkylene urethane and/or (b) alkylene urea moieties and, optionally, (c) a plurality of alkylene carbonate and/or alkyleneoxy moieties, and/or alkylene moieties of greater than 6 carbons, and (2) a plurality of active hydrogen moieties covalently bonded to the backbone or a side chain of the backbone provided that at least one of said active hydrogen moieties is hydroxyl and at least one of said active hydrogen moieties is amino are described. Isocyanate-functional prepolymers are formed by the reaction of these polyahls with polyisocyanates. Polyurethane or polyurea compositions can be formed by the reaction of these isocyanate-functional prepolymers with a polyol or polyamine.
