Patent ID: 8450412

Claim:
A composition comprising the product of melt blending: about 30 to about 60 weight percent of a polyamide; a flame retardant comprising about 10 to about 25 weight percent brominated polystyrene; and about 5 to about 30 weight percent of a polymeric flame retardant synergist selected from the group consisting of mixtures of poly(arylene ether)s and poly(arylene ether)-polysiloxane block copolymers; and wherein the poly(arylene ether)-polysiloxane block copolymer is the product of a process comprising oxidatively copolymerizing a monomer mixture comprising a monohydric phenol and a hydroxyaryl-terminated polysiloxane; wherein at least 80 weight percent of the hydroxyaryl-terminated polysiloxane in the monomer mixture is incorporated into the poly(arylene ether)-polysiloxane block copolymer; wherein the composition comprises less than or equal to 0.1 weight percent of any polymer other than the polyamide, the brominated polystyrene, and the polymeric flame retardant synergist; and wherein all weight percent are based on the total weight of the composition.
