Low temperature flexible PVC blends

摘要

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).
