Abstract

Poly(4,4'-oxydiphenylene pyromelliteimide)(PI(PMDA/DPE)) were prepared from PMDA and DPE as monomers at condition of 0.50% and 280°C in TS10 (mixture of isomers of dibenzyltoluene). Lath-like crystals and particles composed with plate-like crystals were obtained via the crystallization of oligomers during solution polymerization. The products exhibited high crystallinity and high inherent viscosity of 1.17 dig^-1. This implies solid-state polymerization effectively progressed in the crystals of oligomer, because the chain ends in the oligomers crystal were advantageously arranged for polycondensation reaction.
