ABSTRACT:
Novel polyamide copolymers having skeletons of a specific structure are disclosed. The polyamide copolymers have excellent resistance to hydrolysis, low temperature characteristics (low temperature softness), heat aging resistance and mechanical properties as compared to conventional polyamide copolymers. The polyamide copolymers also show excellent efficiencies in fabrication properties and transparency. In particular, the polyamide copolymers having a branched structure in the molecule thereof provide good results.
