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.
