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.
