Claim Text:
1. A composition comprising: a polycarbonate; a copolymer derived from a copolymerization of a vinyl aromatic monomer and an ethylenically unsaturated nitrile monomer; an impact modifier that comprises acrylonitrile-styrene-acrylate; a first gel-type low gloss additive; where the first gel-type low gloss additive is an epoxy cross-linked styrene acrylonitrile dispersed in polycarbonate; a second gel-type low gloss additive; where the second gel-type low gloss additive is an epoxy cross-linked styrene acrylonitrile dispersed in polystyrene; a first polymethylmethacrylate; and a second polymethylmethacrylate; where the first polymethylmethacrylate and the second polymethylmethacrylate are present in a total amount of 1 to 25 wt %, based on the total weight of the composition; and wherein a weight ratio of the first polymethylmethacrylate to a total weight of the first polymethylmethacrylate and the second polymethylmethacrylate is 0.2 to 1.0; and where the first polymethylmethacrylate has a higher melt viscosity than the second polymethylmethacrylate.
