Preparation of Well-oriented Poly(p-phenylene pyromelliteimide) Fiber via Shear-induced Orientation of Poly(amic ethyl ester) Precursor during Polymerization

The orientation of poly (p-phenylene pyromelliteimide) (PPPI) molecules was examined by means of shearing during the gelation of poly(amic ethyl ester) (PAEE) precursor and thermal imidization. The polymerization of 1,4-phenylene diamine (PPDA) and 2,5-diethoxycarbonyl-1,4-benzenedicarbonyl chloride...
