In order to obtain high-strength, high-modulus and thermo-stable fibers, copolyimide fibers were prepared from p-phenylenediamine/pyromellitic dianhydride (PMDA)/3, 3', 4, 4'-biphenyltetra carboxylic dianhydride (BPDA) copolymers by chemical imidization and subsequent hot-drawing. Drawability and tenacity increased with increasing content of BPDA in the copolymers, and PMDA/BPDA (mole ratio 30/70) copolyimide fiber showed tenacity 21.6g/d and initial modulus 1130g/d. Heat durabilities of these copolyimide fibers were much superior to those of para-aramid fibers such as Kevlar® and Technora®.
