Abstract
A thermoplastic composition suitable for making articles having low gloss and good impact resistance at low temperatures is disclosed. The composition contains (A) 10 to 90 percent relative to the weight of the composition (pbw) of an aromatic (co)poly(ester)carbonate, (B) 10 to 90 pbw of first graft (co)polymer containing a graft base selected from the group consisting of polyurethane, ethylene vinyl acetate, silicone, ethylene-propylene diene rubbers, ethylene propylene rubbers, acrylate rubbers, diene rubbers, and polychloroprene, and a grafted phase, (C) 1 to 20 pbw of a linear glycidyl ester functional polymer comprising repeating units derived from one or more glycidyl ester monomers and (D) 1 to 20 pbw of a second graft (co)polymer containing a core and shell wherein the core contains an interpenetrated network of poly(meth)alkyl acrylate and polyorganosiloxane, and wherein the shell contains poly(meth)acrylate.
