View the Complete Application at the US Patent & Trademark Office
Polyamides, and methods of making and using polyamides, that have a difference between melting temperature (T.sub.m) and crystallization temperature (T.sub.c) of at most 20.degree. C. are disclosed herein. Such polyamides can exhibit exceptionally fast crystallization kinetics making them suitable for use as engineering thermoplastics in melt processing methods such as injection molding. Particularly useful polyamides include 1,9-nonamethylene adipamide-co-1,9-nonamethylene terephthalamide copolymers.
