METHOD OF MANUFACTURING AROMATIC POLYESTER RESIN MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a method of simply and inexpensively manufacturing an aromatic polyester resin molding having excellent thermal shrinkage resistance without the need of a complicated apparatus or complicated operation.

SOLUTION: The method of manufacturing the aromatic polyester resin molding includes: impregnating a hydrocarbon compound such as toluene into a film or a preform comprising an aromatic polyester resin such as a polyethylene terephthalate resin and stretching the hydrocarbon impregnated film or preform at a temperature equal to or below (glass transition temperature of the aromatic polyester resin+ 15°C).
