PURPOSE:The titled compositions having higher rates of crystallization and improved moldability, substantially free of strength reduction, by incorporating talc and specified ether compounds into glass fiber reinforced polyethylene terephthalate resin. CONSTITUTION:The titled compositions comprising 30-95wt% polyethylene terephthalate resins (A), 5-60wt% glass fibers (B), 0.1-30wt% talc (C), and 0.1-10wt% ether compounds (D) of the formula (where R1 and R4 each are H or a hydrocarbon group; R2 and R3 each are an alkylene of 2-6C; n is an integer of 1 or higher; m is 0 or an integer of 1 or higher). The combined use of components C and D will raise the rate of crystallization, improve the moldability, and enable the manufacture of moldings of complicated shape easily, substantially free of strength reduction. |
