Patent ID: 7807745

Claim:
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) has at least one residue derived from the polyethylene terephthalate component, and (b) from 5 to 90 wt. % of a polycarbonate component; and (c) from at least 1 wt. % of an impact modifier component, wherein the modified polybutylene terephthalate random copolymer, the polycarbonate component, the impact modifier, and optionally at least one additive, have a combined weight % of 100 wt %; wherein the modified polybutylene terephthalate random copolymer has an ethylene glycol content of from 0.02 to 2 wt %, a diethylene glycol content of from 0.04 to 4 wt %, and a total amount of isophthalic acid groups, ethylene glycol groups, and diethylene glycol groups ranging from 3 to less than or equal to 23 equivalents relative to the total of 100 equivalents of diol and 100 equivalents of diacid groups in the modified polybutylene terephthalate random copolymer.
