Abstract

Polymer mixtures having high tensile strength and good tear propagation resistance, consisting of PA1 (A) from 10 to 95 parts by weight of a graft polymer, PA1 (B) from 0 to 75 parts by weight of a thermoplastic resin component and PA1 (C) from 5 to 60 parts by weight of a copolymer having a sequence type of structure corresponding to the idealized formula (I) EQU (A--X--B).sub.n (I) PA1 wherein PA2 A=polymer of a cyclic carbonate, PA2 B=polymer of another cyclic ester and PA2 X=middle member containing partial structures of both A and B.
