PROBLEM TO BE SOLVED: To provide a vulcanizable rubber composition having excellent low temperature property, processability, resistance to organic chemicals and permeation resistance. SOLUTION: The vulcanizable rubber composition comprises (A) a diene-containing rubber, (B) a nitrile rubber modified-thermoplastic copolymer of an olefinically unsaturated nitrile and an ester of an olefinically unsaturated carboxylic acid and (C) a vulcanizing agent, wherein the amount of (B) is 3-100 pts.wt., preferably 5-75 pts.wt., and more preferably 15-50 pts.wt., per 100 pts.wt. of (A). The composition retains the excellent low temperature property of the diene-containing rubber, but has better processability (characteristics evaluated by releasability, swelling property, green strength, etc.) than that of the diene-containing rubber, as well as improved resistance to attack by organic chemicals, and improved permeation resistance to organic fumes and fluids.
