D-27711 ELASTOMERIC POLYARYLATE GRAFT COPOLYMERS ABSTRACT Novel thermoplastic elastomeric graft copolymers, formed via a cycloaddition reaction of an elastomer con- taining carbon-carbon double bonds with an aromatic poly- ether, end-capped with a 1,2-dihydroarylcyclobutenyl moiety, are described. The materials exhibit improved UV and thermal oxidative stability, attractive mechanical proper- ties, and superior heat resistance. They are uniquely suited for impact modification of various thermoplastics such as polyesters, polyether imides, and the like. S P E C I F I C A T I O N
