| 摘要 |
<p>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.</p> |
