ABSTRACT:
An improved high performance thermally stable polymer is provided. Such polymer is composed primarily of recurring 6-oxy-2-naphthoyl moieties and is preferably a homopolymer of 6-oxy-2-naphthoyl moieties, i.e. poly(6-oxy-2-naphthoate). It is particularly suited for use in the formation of plasma spray coatings and compression or impact molded articles, and has been found to offer a thermal stability which is superior to that of poly(4-oxybenzoate). Small amounts (as described) of other ester-forming moieties and/or amide-forming moieties optionally may also be present.
