A crosslinkable rubber composition comprising 0.2 to 10 parts by weight of an aromatic secondary amine-based anti-aging agent and 0.5 to 20 parts by weight of a polyamine-based crosslinking agent with respect to 100 parts by weight of a nitrile rubber including an α,β-ethylenically unsaturated nitrile unit and an α,β-ethylenically unsaturated dicarboxylic acid monoester unit, and with iodine value of 120 or less. The present invention can provide a crosslinkable rubber composition, providable of a cross-linked rubber excellent in a variety of properties such as mechanical strength and small in compression set, and a cross-linked rubber obtained by cross-linking the rubber composition.
A crosslinkable rubber composition comprising 0.2 to 10 parts by weight of an aromatic secondary amine-based anti-aging agent and 0.2 to 20 parts by weight of a polyamine-based crosslinking agent with respect to 100 parts by weight of a nitrile rubber including an α,β-ethylenically unsaturated nitrile monomer unit and an α,β-ethylenically unsaturated dicarboxylic acid monoester monomer unit and having iodine value of 120 or less.
A crosslinkable rubber composition comprising 0.1 to 20 parts by weight of a primary monoamine having no polar group other than an amino group and 0.1 to 20 parts by weight of a polyamine-based crosslinking agent with respect to 100 parts by weight of a nitrile rubber including an α,β-ethylenically unsaturated nitrile monomer unit and an α,β-ethylenically unsaturated dicarboxylic acid monoester monomer unit and having iodine value of 120 or less.
A crosslinkable rubber composition comprising a nitrile group containing highly-saturated copolymer rubber, a polyoxyalkylene alkyl ether phosphate ester and a polyamine-based crosslinking agent.
A crosslinkable rubber composition comprising 0.2 to 20 parts by weight of a polyamine-based crosslinking agent with respect to a total of 100 parts by weight of a nitrile group containing highly-saturated copolymer rubber having an α,β-ethylenically unsaturated dicarboxylic acid monoester monomer unit and an acrylic rubber having an α,β-ethylenically unsaturated dicarboxylic acid monoester monomer unit.
