TLDR
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 technique, exhibit good physical properties and a low gloss finish as discussed by the authors.
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.

Polycarbonate polyester blends modified with poly(phenylene ether)

TL;DR: Blends of polycarbonate and polyester are admixed in compositions with poly(phenylene ether), and/or with a poly( phenylene ether) concentrate containing poly(polyethylene ether), polystyrene, polyamide, poly carbonate, polyester, poly(alkyl acrylate), and polyethylene methacrylate.
Patent

Reduced gloss thermoplastic compositions and processes for making thereof

TL;DR: Reduced gloss polycarbonate graft polymer blends as discussed by the authors are provided by a process which involves compounding styrene-acrylonitrile copolymer in the presence of an electrophilic reagent and preferably an acid to form gels, and then compounding the resultant gels with poly-carbonate, a styreneacryllitrile Copolymer and ABS graft polymer to form reduced gloss PC/ABS/SAN composition.
