PCT No. PCT/JP90/00527 Sec. 371 Date Dec. 13, 1990 Sec. 102(e) Date Dec. 13, 1990 PCT Filed Apr. 24, 1990 PCT Pub. No. WO90/12818 PCT Pub. Date Jan. 11, 1990.The higher alpha -olefin copolymers obtained in accordance with the present invention are copolymers derived from higher alpha -olefin and non-conjugated diene represented by the following general formula [I], and (a) the non-conjugated diene content thereof is from 0.01 to 30 mol %, and (b) the intrinsic viscosity [ eta ], as measured in decahydronaphthalene at 135 DEG C., of said copolymer is from 1.0 to 10.0 dl/g. <IMAGE> [I] The invention also provides a process for preparing such higher alpha -olefin copolymers as illustrated above, and vulcanization products obtained from said copolymers. Furthermore, the invention provides vulcanizable compositions containing rubber comprising of the above-mentioned higher alpha -olefin copolymers and a specific diene rubber or a specific ethylene/ alpha -olefin copolymer rubber.
