Abstract: A polymer composition includes 15 to 60 wt %, preferably 20 to 56 wt % of a polycarbonate; 30 to 60 wt %, preferably 28 to 50 wt % of a poly(1,4-cyclohexanedimethylene terephthalate); 0.05 to 35 wt %, preferably 0.1 to 30 wt % of a poly(carbonate-siloxane); 0.5 to 18 wt %, preferably 1 to 13 wt % of a thermoplastic poly(ester-ether) copolymer, preferably comprising poly(butylene terephthalate) blocks and poly(oxyC1-C4 alkylene units); and 0.5 to 8 wt % of ethylene-alkyl (meth)acrylate copolymer, wherein alkyl is a C1-C4 straight chain, unsaturated hydrocarbon group; wherein the weight percentages are based on the total weight of the polymer composition. A method of manufacturing an article including the steps of melt blending the components of the polycarbonate composition is described. An article prepared by the method is also described.
