ABSTRACT:
Dispersions of core-shell polymers in caprolactam solutions of telechelic polymers capable of being polymerized to form rubber-modified nylon-6 block copolymers having improved impact strength wherein the core-shell polymer comprises a cross-linked elastomer core and a hard thermoplastic polymer shell and wherein the telechelic polymers preformed or formed in situ, are capped with lactam polymerization initiator groups.
