摘要

A molding composition comprising (a) from 5 to 90 wt % of a modified polybutylene terephthalate random copolymer that (1) is derived from polyethylene terephthalate component selected from the group consisting of polyethylene terephthalate and polyethylene terephthalate copolymers and (2) at least one residue derived from the polyethylene terephthalate component, and (b) from 5 to 40 wt % of a polyalkylene terephthalate component; wherein the modified polybutylene terephthalate random copolymer, the polyalkylene terephthalate component, and optionally, at least one additive, have a combined weight % of 100 wt %. Methods for making the composition and articles made from the composition.
