ABSTRACT:
Low temperature impact properties of poly(vinyl chloride) are improved by adding to the poly(vinyl chloride) chlorosulfonated polyethylene and chlorinated polyethylene wherein the base polyethylene of each additive has a density of at least 0.94. The use of all three components provides a synergistic lowering of the brittleness temperature as compared to either chlorosulfonated polyethylene or chlorinated polyethylene when added to the poly(vinyl chloride).
