ABSTRACT:
A novel polyester is provided which is capable of forming an anisotropic melt and which, subsequent to being formed into shaped articles, is capable of crosslinking to render the article highly heat stable. The polyester preferably consists of approximately 1 to 40 mole percent of 3-allyl-4-oxybenzoyl and/or 3-methylallyl-4-oxybenzoyl moieties copolymerized with oxyaroyl moieties and/or dioxaryl and dicarboxyaryl moieties. The process comprises heating a monomer mixture of allylically substituted hydroxybenzoic acid and aromatic hydroxy acids and/or aromatic diols and diacids to prepare the polyester; melt processing the polyester to form a solid shaped article; and heating to substantially crosslink the allylic groups while substantially retaining the configuration of the solid shaped article.
