Abstract
Compositions which have substantial weatherability and impact resistance comprise a substantially uniform physical blend of an uncross-linked acrylonitrile/styrene copolymer and a cross-linked alkyl acrylate/graft (meth)acrylate copolymer. Methods for making such compositions include forming a substantially uniform physical blend of such copolymers. The compositions preferably are substantially free of cross-linked acrylonitrile/styrene copolymer.
Claims21
A weatherable composition comprising a physical blend having a substantially uniform make-up and including at least about 30% by weight, based on the total weight of the composition, of an uncross-linked acrylonitrile/styrene copolymer and at least about 5% by weight, based on the total weight of the composition, of a cross-linked alkyl acrylate/graft (meth)acrylate copolymer, said composition being substantially free of cross-linked acrylonitrile/styrene copolymer.
A composition comprising a physical blend of an uncross-linked acrylonitrile/styrene copolymer and a cross-linked alkyl acrylate/graft (meth)acrylate copolymer, said blend having a substantially uniform make-up, said composition being weatherable and substantially free of cross-linked acrylonitrile/styrene copolymer.
A method for forming a weatherable resin composition comprising:
- providing an uncross-linked acrylonitrile/styrene copolymer;
- providing a cross-linked alkyl acrylate/graft (meth)acrylate copolymer;
- and
- forming a physical blend of said uncross-linked acrylonitrile/styrene copolymer and said cross-linked alkyl acrylate/graft (meth)acrylate copolymer, said physical blend having a substantially uniform make-up and being substantially free of cross-linked acrylonitrile/styrene copolymer.
