Patent ID: 7855238

Claim:
A molding composition consisting essentially of: (a) from 5 to 90 wt % of a modified polybutylene terephthalate random copolymer having a melting temperature that is at least 200 ° C. and that (1) is derived from a depolymerized 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 depolymerized polyethylene terephthalate component comprising diethylene glycol groups in the amount of from 0.1 to 10 mole %, based on 100 mole % of glycol in the modified polybutylene terephthalate random copolymer, (b) from 5 to 40 wt % of a polyalkylene terephthalate component selected from the group consisting of polycyclohexane_dimethylene terephthalate, polytrimethylene terephthalate, poly-xylylene terephthalate, polydialkanolterephthalates, polybutylene terephthalate, and combinations thereof, (c) optionally, a filler, (d) optionally, at least 0.01 wt % of a carboxy reactive material, (e) optionally, an ultraviolet stabilizer in an amount of ranging from 0.05 to 1 wt %, and (f) optionally, an additive selected from the group consisting of flame retardants, stabilizers, quenchers, mold release agents, teflon-styrene acrylonitrile mixtures, impact modifiers, and combinations thereof; wherein components (a), (b), (c), (d), (e), and (f) have a total combined weight % of 100 wt %.
