Abstract
Thermoplastic compositions of a polyamide with a thermoplastic polyester, polycarbonate, poly(ester carbonate) or polyarylate resin compatibilized with a polyamide-polyester block copolymer have excellent physical properties after molding and show no evidence of delamination.
Claims22

- (i) a high molecular weight thermoplastic resin selected from a thermoplastic polyester, an aromatic polycarbonate, a poly(ester carbonate) or a mixture of any of the foregoing.
- (ii) an amorphous polyamide resin;
- and
- (iii) an effective, compatibilizing amount of a polyamide-polyester block copolymer.
