Abstract

Provided are a blended rubber and a blended rubber composition that give a vulcanizate superior in abrasion resistance and ozone resistance, and a vulcanizate prepared by vulcanizing the blended rubber composition. A blended rubber, comprising 30 to 93 mass % of a chloroprene rubber, 5 to 50 mass % of a soft polyvinyl chloride, and 2 to 20 mass % of an acrylonitrile-butadiene rubber. The polyvinyl chloride resin used preferably has a polymerization degree of 300 to 3000 and the acrylonitrile-butadiene rubber preferably has an acrylonitrile content of 18 to 50 mass %.
