Patent ID: 7659334

Claim:
An impact resistant rigid vinyl chloride polymer composition consisting essentially of: a vinyl chloride polymer; 2 to 5 parts by weight of an impact modifier system, based on 100 parts of said vinyl chloride polymer, wherein said impact modifier system comprises: a chlorinated olefin polymer; and an ethylene/alpha-olefin copolymer; and a lubricant system comprising: 0.5 to 1.5 parts by weight of a carboxylic acid, based on 100 parts of said vinyl chloride polymer, wherein said carboxylic acid is selected from the group consisting of stearic acid, lauric acid, myristic acid, palmitic acid, blends thereof, and combinations thereof; 0.3 to 2.0 parts by weight of a hydrocarbon wax, based on 100 parts of said vinyl chloride polymer, wherein said hydrocarbon wax is selected from the group consisting of a paraffin wax, polyolefin wax, blends thereof, and combinations thereof; and 0.3 to 1.5 parts by weight of a metal soap, based on 100 parts of said vinyl chloride polymer, wherein said metal soap is selected from the group consisting of calcium stearate, aluminum stearate, copper stearate, lithium stearate, magnesium stearate, sodium stearate, zinc stearate, blends thereof, and combinations thereof.
