ABSTRACT:
Novel isocyanate-terminated polyether-based polymer prepolymers useful in urethane applications are produced by polymerization of one or more ethylenically unsaturated monomers in the presence of an isocyanate-terminated prepolymer obtained by reaction of an organic polyisocyanate with a polyhydroxy-containing adduct obtained by reacton of an alkylene oxide with a polyfunctional initiator containing two to six active hydrogen atoms. These isocyanate-terminated polyether-based polymers prepolymer compositions are useful in the preparation of flexible urethane foams and moisture-cured adhesives.
