| 摘要 |
A blend of a rubber and a rubber modifier, the rubber modifier comprising an ethylene/alpha-olefin copolymer rubber (A) composed of one or more copolymers selected from the group consisting of a copolymer of ethylene and an alpha-olefin having 3-20 carbon atoms and a copolymer of ethylene, an alpha-olefin having 3-20 carbon atoms and a non-conjugated polyene, the copolymer rubber (A) having the parameters:an ethylene/alpha-olefin mole ratio in the range of 51/49 to 87/13,an intrinsic viscosity [eta] determined in decahydronaphthalene at 135° C. in the range of 0.8 to 2.5 dl/g andan iodine value in the range of 0 to 40.
