Abstract
Blends of (A) an impact resistant interpolymer comprising crosslinked acrylic or methacrylic rubber, crosslinked styrene-acrylonitrile and uncrosslinked styrene-acrylonitrile polymer components, (B) an acrylic polymer, and (C) a multistage grafted acrylic elastomer are disclosed. The blends display a good combination of physical properties including gloss, impact strength and tensile properties.
Claims8
A weatherable impact resistant resin composition comprising:
- (A) 5 to 95 parts of weight of an acrylate-styrene-acrylonitrile terpolymer resin;
- (B) 95 to 5 parts by weight of an acrylic resin made by the polymerization of acrylic ester monomers;
- and
- (C) 1 to 40 parts by weight per 100 parts of resins (A) and (B) taken together of an impact modifying component
- wherein said modifying component is comprised of a crosslinked alkyl acrylate-graft acrylate copolymer.
