Abstract
A blend of a vinyl chloride polymer, and a crosslinked (meth)acrylate/crosslinked styrene-acrylonitrile/uncrosslinked styrene-acrylonitrile impact modifier is disclosed. The presence of the impact modifier gives the blend improved impact resistance as compared to the vinyl chloride polymer alone. The impact modifier also functions as a heat distortion temperature improver and process aid for the vinyl chloride polymer.
