PURPOSE:To obtain a rubber composition having excellent appearance, electric conductivity and antistatic properties, etc., without blooming containing synthetic rubber and an alkylene oxide adduct of a saponified ethylene-saturated carboxylic acid vinyl ester copolymer. CONSTITUTION:The aimed composition contains (A) 100 pts.wt. synthetic rubber (preferably ethylene-alpha-olefin copolymer rubber) and (B) 0.5-10 pts.wt., preferably 1-5 pts.wt. alkylene oxide adduct of a saponified product of ethylene-saturated carboxylic acid vinyl ester copolymer (preferably the saturated carboxylic acid vinyl ester is vinyl acetate and saponification degree is 30-100%). |
