WEATHERABLE STYRENIC BLENDS WITH IMPROVED TRANSLUCENCY

摘要

Rubber modified weatherable styrenic blends with improved transparency and colorability are disclosed. A matrix phase of poly(alkyl alkylacrylate) and vinyl carboxylic acid ester-vinyl aromatic-vinyl cyanide is combined with a rubbery graft phase of a poly(alkyl acrylate) rubber substrate grafted with a vinyl aromatic-vinyl cyanide superstrate copolymer to provide acrylate-styrene-acrylonitrile type (ASA) compositions.
