THERMOPLASTIC POLYESTER COMPOSITIONS, METHODS OF MANUFACTURE, AND ARTICLES THEREOF

摘要

A thermoplastic polyester composition comprises, based on the total weight of the composition, from 20 to 95 wt.% of a polyester comprising a poly(alkylene terephthalate); from 1 to 35 wt.% of a phosphorous flame retardant consisting of a phosphinate of the formula (I) [(R1)(R2)(PO)-O]mMm+ (I), a diphosphinate of the formula (II) [(O-POR)(R3)(POR2-O)]2-nMm+x (II), and/or a polymer derived from the phosphinate of formula (I) or the diphosphinate of the formula (II); from 0.1 to less than 20 wt.% of a copolyetherester; from 0.1 to 5 wt.% of an anti-dripping agent; from 0 to 4.5 wt.% of a reinforcing fiber; and from 0 to 5 wt.% of an additive selected from the group consisting of a mold release agent, an antioxidant, a thermal stabilizer, and a UV stabilizer.
