Blend of impact modifier, vinyl chloride polymer, and acrylic resin.

摘要

Polymer blends having good hardness and flame retardancy comprise: (1) an interpolymer comprising: (a) crosslinked (meth)acrylate; (b) crosslinked styreneacrylonitrile polymeric components; and (c) uncrosslinked styrene acrylonitrile components (2) an acrylic resin; and (3) a vinyl chloride polymer. The amount of interpolymer (1) in the blend predominates over the respective weight amounts of either of the two other components (2) and (3).
