PURPOSE:To obtain a rubber vibration isolator excellent in vibration-isolating properties and fatigue resistance by molding a rubber composition comprising a specified chloroprene polymer and a 2,3-dichlorobutadiene 1,3-polymer and vulcanizing the obtained molding. CONSTITUTION:A rubber composition comprising a chloroprene polymer containing at least 80wt.% chloroprene units and a 2,3-dichlorobutadiene-1,3 polymer containing at least 70wt.% 2,3-dichlorobutadiene-1,3 units is molded and vulcanized. |
