The present invention provides a vulcanizable rubber composition comprising 100 parts by weight of a polymer component consisting of 30 to 80 wt. % of an ethylene.cndot..alpha.-olefin.cndot.non-conjugated diene copolymer having a Mooney viscosity of 10 to 100 (ML.sub.1+4 100.degree. C.) and an iodine value of 20 to 45 and containing ethylene and .alpha.-olefin in a weight ratio of 50:50 to 90:10, and 20 to 70 wt. % of a styrene-conjugated diolefin block copolymer, 20 to 150 parts by weight of a reinforcing filler, 3 to 30 parts by weight of sulfur, 0 to 50 parts by weight of a styrene resin and 0 to 100 parts by weight of an extending oil.

Vulcanizable rubber compositions and vulcanized rubber

Adhesiveness of a halogenated butyl rubber is improved by blending with it from 5 to 20 weight parts of nickel dithiocarbamate, such as nickel butyl- or diethyldithiocarbamate, per 100 weight parts of the rubber.

Rubber with nickel dithiocarbates

An adhesive composition useful for adhesion of rubber to metal is produced by dissolving a chlorinated type polymer and a petroleum resin, optionally in combination with a dithiocarbamate, in an organic solvent.
