Abstract: Blends of carbonate polymer, such as a polycarbonate of bisphenol-A, and a rubber-modified copolymer, such as an acrylonitrile/butadiene/styrene (ABS) resin prepared by mass, bulk or mass suspension polymerization techniques, provide articles which exhibit good low temperature physical properties and can exhibit a low gloss finish. Such blends are particularly useful in the manufacture of molded parts. Such blends are color stable and can exhibit small amounts of yellowing. Such blends are particularly useful in low temperature applications such as below about 0.degree. F.

Abstract: Blends of carbonate polymer, such as a polycarbonate of bisphenol-A, and a rubber-modified copolymer, such as an acrylonitrile/butadiene/styrene (ABS) resin prepared by mass, bulk or mass suspension polymerization techniques, or by agglomerating particles prepared by emulsion polymerization techniques, exhibit good physical properties and a low gloss finish. Such blends are particularly useful in the manufacture of molded parts. Such blends are color stable and exhibit small amounts of yellowing.

Abstract: Novel copolycarbonates exhibiting generally improved impact resistance, clarity and flame resistance are prepared by blending a polycarbonate of a trityldiol such as phenolphthalein and a polycarbonate of another diol such as bisphenol-A under conditions of temperature and/or shear sufficient to cause reaction of the polycarbonates.
