ABSTRACT:
Physical blends of solid particulates of chlorinated polyolefins and elastomeric ethylene copolymers yield a blended product with anti-blocking characteristics superior to that defined by the weight proportion-based linear interpolation of either blend component. The blend compositions are useful as impact modifiers for polyvinyl chloride compositions.
