Patent ID: 7851532

Claim:
A flame retardant thermoplastic polyester resin composition comprising: (A) about 100 parts by weight of a polyester resin, wherein said polyester resin (A) comprises polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, polyethylene naphthalate, polypropylene naphthalate, polybutylene naphthalate, polyethylene dibenzoate, a copolyester thereof, or a combination thereof; (B) about 1 to about 60 parts by weight of a cyclic oligomeric phosphazene compound, wherein said cyclic oligomeric phosphazene compound (B) is represented by the following Formula 1: wherein R 1 is C 1 -C 20 alkyl, C 6 -C 30 aryl, C 6 -C 30 alkyl substituted aryl, C 6 -C 30 arylakyl, C 1 -C 20 alkoxy, C 6 -C 30 aryloxy, amino, or hydroxyl group, wherein the alkoxy or aryloxy can optionally be substituted with alkyl, aryl, amino, or hydroxyl, each k and m is independently 0 or integers from 1 to 10; R 2 is C 6-30 dioxyaryl or alkyl substituted C 6-30 dioxyaryl derivative; and n is a number-average degree of polymerization and the average value of n is from about 0.3 to about 3; (C) about 1 to about 50 parts by weight of a melamine compound; (D) about 1 to about 20 parts by weight of a inorganic metal compound; and (E) about 0.1 to about 5 parts by weight of a fluorinated polyolefin resin.
