ABSTRACT:
In accordance with a preferred embodiment of this invention, a family of alkylene-linked aromatic polyimides is synthesized. These polymers are thermally stable at a temperature of at least 400.degree. C. and processible in conventional thermoplastic processing equipment. Such new and useful polymers are produced by employing an alkylene-linked dixylene which is oxidized and dehydrated to form the corresponding dianhydride. This alkylene-linked dianhydride is then reacted, through a condensation polymerization reaction, with any of many known diamine terminated compounds to form the subject polyimide resins.
