Abstract

PURPOSE:To obtain polyester molded articles having excellent mechanical and thermal properties and good appearance, by molding the specified polyester copolymer at the specified range of the mold temperature, further heat-treating the molded article under the specified conditions. CONSTITUTION:Copolymerized polyester composed of polyethyleneterephthalate unit and /or polyethyleneisophthalate unit 20-50mol% and polyethylene-4,4'- diphenyldicarboxylate unit 80-50mol% is injection molded, preferably at the mold temperature 40-120 deg.C, and further the molded article is stood still in the range of 100-150 deg.C in the heating oven, preferably heat-treated by heating more than one hour, thus the desired molded article is obtained.
