PROBLEM TO BE SOLVED: To provide a PVC latex for NBR and PVC compositions to produce NBR and PVC compositions with excellent storage stability, mechanical strength and improved dynamic viscoelasticity; and NBR and PVC compositions.SOLUTION: Provided are: PVC latex for nitrile rubber (NBR) and vinyl chloride polymer (PVC) compositions where 1 to 5 pts.wt. of alkylbenzenesulfonate and 0.05 to 2.5 pts.wt. of higher fatty acid salt relative to 100 pts.wt. of vinyl chloride polymer are contained, and the vinyl chloride polymer has an average particle diameter of 0.20 μm or less and an average polymerization degree of 400 to 2000; and NBR and PVC compositions. |
