ABSTRACT:
Thermally stable, highly fused imide polymers are prepared by reacting 2,2'-bis(phenylethynyl)-4,4'-diaminobiphenyl or 2,2'-bis-(phenylethynyl)-5,5'-diaminobiphenyl with an aromatic dianhydride. The polyimides are particularly suitable for use in high temperature applications, such as in the fabrication of fiber reinforced structural composites, fibrous materials and protective coatings.
