Abstract:
A vinyl chloride polymer composition comprising:a) a polyvinyl chloride resin having at least 70 wt. % repeat units from a vinyl chloride monomer and up to 30 wt. % repeat units from other comonomers;b) a chlorinated polyethylene having an amorphous phase and a crystalline phase wherein said chlorinated polyethylene contains bound chlorine (% Cl) in an amount of from about 20 to about 50 weight percent based upon the weight of said chlorinated polyethylene, wherein said chlorinated polyethylene has a residual crystallinity equal to or greater than -0.068.times.(% Cl).sup.2 +2.59.times.(% Cl)+74.71, wherein said % Cl is weight percent bound chlorine in the chlorinated polyethylene, and wherein said chlorinated polyethylene has a melting temperature of from about 110.degree. C. to about 140.degree. C. when measured by differential scanning calorimetry; andc) a polyolefin elastomer dispersed in said polyvinyl chloride composition, said elastomer as dispersed having a number average particle diameter of less than 25 .mu.m.
