Blend of impact modifier, vinyl chloride polymer, and glassy amorphous polymer

摘要

Polymer blends having good mechanical properties and flame retardancy comprise: (1) an interpolymer comprising: (a) crosslinked (meth)acrylate; (b) crosslinked styrene-acrylonitrile polymeric components; (2) a glassy amorphous polymer, e.g., an acrylic resin or a polymer comprising styrene; and (3) a vinyl chloride polymer.
