PCT No. PCT/JP94/00528 Sec. 371 Date Sep. 29, 1995 Sec. 102(e) Date Sep. 29, 1995 PCT Filed Mar. 31, 1994 PCT Pub. No. WO94/22947 PCT Pub. Date Oct. 13, 1994This invention relates to a vulcanizable rubber composition obtained by compounding, into an ethylenically unsaturated nitrile-conjugated diene copolymer rubber, a zinc compound, an alpha , beta -ethylenically unsaturated carboxylic acid, a compound of a 2A Group metal of the periodic table and an organic peroxide. The vulcanizable rubber composition of this invention can provide a vulcanized rubber having excellent heat resistance and oil resistance and moreover possessing high tensile stress or stably exhibiting high tensile strength without being affected by kneading conditions, and is hence suitable for use as a rubber material for toothed belts and the like. |
