MODIFIED BLOCK COPOLYMERS, IMPACT RESISTANT COMPOSITIONS CONTAINING THE COPOLYMERS AND A PROCESS FOR PRODUCING THE COPOLYMERS

摘要

MODIFIED BLOCK COPOLYMERS Thermally stable modified selectively hydrogenated high 1,2-content block copolymer wherein a functional group is grafted to the block copolymer in the monoalkenyl-arene block and impact resistant polymeric compositions comprising: (a) 3-50% by weight of such modified block copolymers, and (b) 50-97% by weight of polyamide having a number average molecular weight of at least 5,000 or a thermoplastic polyester.
