PURPOSE:To provide the titled colorable composition having excellent thermal aging resistance, by adding a specific process oil to a chloroprene rubber. CONSTITUTION:100pts.wt. of a chloroprene rubber is compounded with 2-40pts. wt. of process oil containing >=5wt% aromatic carbon composition. Although a sufficiently high thermal aging resistance can be imparted to the rubber by the addition of the above process oil, a non-polluting and non-coloring phenolic antiaging agent is used in the case of using additional antiaging agent. |
