Improved injection moldability of polyethylene terephthalates is achieved by the addition of small amounts of at least one monoepoxyalkane. The injection moldability is further improved by the further addition of small amounts of an adjuvant synergistically cooperative with the monoepoxyalkane. The improved moldability and mold releasability is achieved even when the composition is injection molded at mold temperatures of at least as low as 93.degree. C.
