Abstract:
1. A composition comprising: 60 to 95 weight percent of a poly(phenylene ether)-polysiloxane block copolymer reaction product comprising 5 to 40 weight percent of an impact modifier; wherein the impact modifier comprises poly(alkenyl aromatic) content and rubber content, wherein the weight ratio of poly(alkenyl aromatic) content to rubber content is at least 0.5, and wherein the impact modifier comprises a rubber-modified polystyrene; wherein the composition comprises 1 to 10 weight percent of polysiloxane covalently bound in the poly(phenylene ether)-polysiloxane block copolymer; wherein the composition comprises less than or equal to 10 parts by weight of polysiloxane not covalently bound in the poly(phenylene ether)-polysiloxane block copolymer relative to 100 parts by weight of polysiloxane covalently bound in the poly(phenylene ether)-polysiloxane block copolymer; wherein the composition comprises 0 to 0.5 weight percent of organophosphate esters; wherein the composition comprises 0 to 0.5 weight percent of halogens; and wherein all weight percents are based on the total weight of the composition.
