PURPOSE:The titled composition having high heat distortion temperature without lowering mechanical strength, providing a molded article having improved releasability, etc., obtained by blending a polyethylene terephthalate resin with a mono-, di-, or polybenzoate of a specific polycaprolactone and a metal salt of organic carboxylic acid. CONSTITUTION:(A) 30-85wt% polyethylene terephthalate is blended with (B) 5-60wt% glass fibers, (C) 0.03-5wt% at least one organic acid metal salt of I a or IIa group of periodic table, and (D) 0.1-20wt% mono-, di-, or polybenzoate of polycaprolactone having 300-5,000, preferably 500-2,000 number-average molecular weight. The component B is glass fibers of chopped strand type and used in such a way that 0.4-6mm. glass fibers are processed into 0.2-2mm. glass fibers in a final molded article. Sodium stearate, sodium benzoate, etc. is preferable as the component C.
