Abstract

PURPOSE: A polybutylene terephthalate polymer composition with excellent moldability, prepared by the incorporation of a thermoplastic polymer of secondary transition temp. ≥80°C.
CONSTITUTION: A polybutylene terephthalate polymer composition is obtd. by compounding a polyester consisting of a tetramethylene terephthalate unit (a polymer obtd. by the condensation of 1,4-butanediol with tetrephthalic acid or dimethyl ester), with about 0.1W5wt% thermoplastic polymer of secondary transition temp. ≥80°C (e.g., polystyrene or polymethyl methacrylate. It is possible to spin said composition with good moldability (at a spinning rate of about 300W2,500m/min at melt spinning temp. of about 250W290°C) and to stretch an unstretched filament at least about three fold at a stretch temp. ≥about 30°C.
