This disclosure is concerned with a process for injection molding polyethylene terephthalate into colder molds, i.e., less than 120 DEG C., and still obtaining crystalline parts by incorporating an organic imide containing compound having a melting point in excess of 240 DEG C. into the composition. The presence of this additive enhances the crystallization velocity of the composition and permits the achievement of crystalline parts with optimum properties with colder molds and shorter molding cycles than are conventional for polyethylene terephthalate molding compositions.
