ABSTRACT:
Carbonate polymer compositions comprise extruded blends of a carbonate polymer and a copolymer consisting essentially of a monovinylidene aromatic comonomer and an .alpha.,.beta.-ethylenically unsaturated comonomer having a polar group. Optionally, a small amount of monovinylidene copolymer can be blended with said composition. Such compositions exhibit high impact strengths, improve the melt processability of the carbonate polymer and are advantageously highly transparent and exhibit low haze.
