METHOD FOR PRODUCING POLYCARBONATE AND/OR POLYETHYLENE TEREPHTHALATE MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a PC and/or PET molding crystallized or made into a pre-crystallization structure, with which orientation of PC and/or PET by a magnetic field that has been impossible can be attained. SOLUTION: This method for producing a crystallized PC and/or PET molding is characterized in that an organic alkali metal salt is mixed with a bisphenol A polycarbonate(PC) and/or polyethylene terephthalate(PET), melted and kneaded, and the PC composition obtained by kneading and added with additives is molded into a specified shape, and the obtained molding is subjected to a prescribed heat treatment while applying magnetic field having a given intensity and direction to the molding and is completely or partially crystallized so that the molding has orientation of crystal or pre-crystallization structure in a given direction.
