ABSTRACT:
Thermoplastic poly(imide-esters) and poly(imide-amides) with repeat units derived from the title amino acid. In the polymer the amino group becomes part of an imide group and the carboxyl group becomes part of an ester or amide group. The polymers have a good balance of properties, making them useful for melt forming shaped articles, films and fibers.
