Abstract (en)

[origin: EP0832926A1] A rubber modifier which can improve the workability in roll kneading and in extrusion of rubber without deteriorating the material properties of the rubber and which is superior in the performance of handling and working is provided. The rubber modifier comprises 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 Ä eta Ü determined in decahydronaphthalene at 135 DEG C in the range of 0.8 to 2.5 dl/g and an iodine value in the range of 0 to 40.
