POLYMER COMPOSITIONS, METHOD OF MANUFACTURE, AND ARTICLES FORMED THEREFROM

摘要

A composition comprises, based on the total weight of the composition: from 10 to 80 wt. % of a modified polybutylene terephthalate copolymer that (1) is derived from polyethylene terephthalate component selected from the group consisting of polyethylene terephthalate and polyethylene terephthalate copolymers and (2) has at least one residue derived from the polyethylene terephthalate component; from 10 to 80 wt. % of a polycarbonate; from 0 to 20 wt. % of an impact modifier; from 1 to less than 25 wt. % of a reinforcing filler; from 0.1 to less than 2.5 wt. % of a fibrillated fluoropolymer; from 0 to 5 wt. % of an additive selected from the group consisting of antioxidants, mold release agents, colorants, quenchers, stabilizers, and combinations thereof. The composition has a heat deflection temperature of at least 110° C., measured in accordance with to ASTM D648 on 3.2 mm thick molded bars at 0.455 MPa.
