US 2006/0148992 A1 · Thermoplastic resin composition having improved external appearance and excellent weatherability

Abstract

The present invention relates to an acrylonitrile (ASA) type thermoplastic resin composition with excellent weatherability and appearance properties, and more particularly, to an acrylate-styrene-acrylonitrile type thermoplastic resin composition comprising a) an acrylate-styrene-acrylonitrile graft copolymer; b) a butadienc-acrylonitrile mcthylmethacrylate graft copolymer; c) a copolymer of aromatic vinyl compound and vinylcyanide compound; and d) an alkyl acrylate copolymer, which has remarkably improved appearance properties such as scratch resistance, color (color stability) and gloss as well as excellent basic properties and weatherability.
