Abstract:
1. A thermoplastic composition comprising: 30 to 65 weight percent poly(arylene ether) having an initial intrinsic viscosity greater than 0.25 dl/g as measured in chloroform at 25° C.; 20 to 40 weight percent a polyolefin having a melt temperature greater than or equal to 120° C. and a melt flow rate of 0.3 to 15; a first block copolymer having a aryl alkylene content greater than or equal to 50 weight percent based on the total weight of the first block copolymer; a second block copolymer having an aryl alkylene content less than 50 weight percent based on the total weight of the second block copolymer; and a flame retardant, wherein the poly(arylene ether) is present in an amount by weight greater than the amount of polyolefin by weight, the combination of block copolymers is present in an amount of 2 to 20 weight percent, weight percent of poly(arylene ether), polyolefin and block copolymers is based on the combined weight of the poly(arylene ether), polyolefin, and block copolymers, and the composition comprises less than 0.1 weight percent polysiloxane based on the total weight of the thermoplastic composition.
