Patent ID: 7799854

Claim:
A flame retardant thermoplastic composition comprising: 15 to 35 weight percent of a poly(arylene ether); 15 to 50 weight percent of a block copolymer; 3 to 12 weight percent of a liquid polyolefin; 2 to 15 weight percent of a phosphoric acid salt selected from the group consisting of melamine phosphate, melamine pyrophosphate, melamine orthophosphate, melem polyphosphate, melam polyphosphate, diammonium phosphate, monoammonium phosphate, phosphoric acid amide, melamine polyphosphate, ammonium polyphosphate, polyphosphoric acid amide, and combinations of two or more of the foregoing; 2 to 10 weight percent of a metal hydroxide; and 5 to 20 weight percent of an organic phosphate, wherein the block copolymer comprises a block that is a controlled distribution copolymer having terminal regions that are rich in alkylene units and a center region that is rich in aryl alkylene units, and further wherein weight percent is based on the total weight of the composition.
