Abstract:
1. A thermoplastic composition comprising, based on the total weight of the composition, 88 to 98 wt % of a poly(carbonate-arylate ester), wherein the poly(carbonate-arylate ester) is a poly(carbonate-monoaryl arylate ester), a poly(carbonate-monoaryl arylate ester) comprising siloxane units, or a combination comprising at least one of the foregoing; and 2 to 12 wt % of bisphenol A bis(diphenyl phosphate); optionally, up to 5 wt % of an additive selected from a processing aid, a heat stabilizer, an ultra violet light absorber, a colorant, or a combination comprising at least one of the foregoing, wherein an article molded from the composition has wherein the poly(carbonate-monoaryl arylate ester) comprises repeating carbonate units of the formula wherein wherein wherein the poly(carbonate-monoaryl arylate ester) comprising siloxane units comprises repeating carbonate units of the formula wherein wherein siloxane units of the formula wherein wherein poly(carbonate-arylate ester) is a combination of a poly(bisphenol-A carbonate)-co-poly(isophthalate-terephthalate-resorcinol ester) and a poly(bisphenol-A carbonate)-co-poly(isophthalate-terephthalate-resorcinol ester)-co-poly(siloxane) comprising, a based on the total weight of the poly(carbonate-arylate ester)s, 20 to 80 wt % of the poly(bisphenol-A carbonate)-co-poly(isophthalate-terephthalate-resorcinol ester); and 20 to 80 wt % of the poly(bisphenol-A carbonate)-co-poly(isophthalate-terephthalate-resorcinol ester)-co-poly(siloxane) which comprises siloxane units of the formula
