Abstract

PURPOSE:To obtain an aromatic polyimide polymer molding having a high strength, a high modulus of elasticity and excellent heat resistance, by molding a polyimide (co)polymer having specified recurring units or a polyamic acid polymer as a precursor thereof and stretching the molding. CONSTITUTION:A polyimide polymer mainly consisting of recurring units of formula I (wherein R1 is a tetravalent aromatic group of formula II, III, IV or the like), a polyimide copolymer mainly consisting of recurring units of formula I and recurring nits of formula V or a polyamic acid polymer as a precursor thereof is molded into film, fiber or the like, and stretched to obtain the purpose aromatic polyimide polymer molding. In this way, a molding excellent in strength, modulus of elasticity, etc. can be obtained. The obtained molding can be suitably used as a base film of magnetic recording, a heat-resistant reinforcing fiber, or the like.
