ABSTRACT:
Blends of ar,ar'-dihydroxytrityl polycarbonates, such as a copolycarbonate of phenolphthalein and bisphenol-A, with a rubber-modified monovinylidene aromatic copolymer, such as an ABS resin, exhibit improved impact strength, melt flow properties and heat resistance. Such blends are particularly useful in the manufacture of molded parts which must be exposed to high temperatures during manufacture and/or use.
