(57) Abstract: The unsaturated elastomer composition of the present invention comprises: (A) an unsaturated olefin copolymer comprising at least one α-olefin having 2 to 20 carbon atoms, a conjugated diene monomer represented by the following formula (I), and if necessary, an aromatic vinyl compound; , (B) at least one rubber selected from diene rubbers and ethylene / α-olefin / non-conjugated polyene copolymer rubbers, and the weight ratio of the component (A) to the component (B) [( A) / (B)] is 1 / It is characterized by being in the range of 99 to 99/1. Embedded image [In the formula (I), R 1 and R 2 are each independently a hydrogen atom, an alkyl group or an aryl group having 1 to 8 carbon atoms, and at least one of R 1 and R 2 is a hydrogen atom. [Effect] From the above composition, a vulcanizate having excellent heat resistance, weather resistance, ozone resistance, and dynamic fatigue resistance, and excellent vibration damping properties, vibration damping properties, and strength properties can be obtained. |
