    摘要: A nitrile group-containing highly saturated copolymer rubber which is a product obtained by hydrogenating the conjugated diene portion of an unsaturated nitrile-conjugated diene copolymer. The highly saturated copolymer rubber has an alkylthio group having 12 to 16 carbon atoms, which include at least three tertiary carbon atoms, and having a sulfur atom which is directly bound to at least one of the tertiary carbon atom, and the highly saturated copolymer rubber further has a Mooney viscosity of 15 to 200 and an iodine value not larger than 80. The highly saturated copolymer rubber is produced copolymerizing an unsaturated nitrile, a conjugated diene and an optional copolymerizable monomer by using as a molecular weight modifier an alkylthiol compound having 12 to 16 carbon atoms, which include at least three tertiary carbon atoms, and having a sulfur atom which is directly bound to at least one of the tertiary carbon atoms; and then, hydrogenating the thus-obtained copolymer. The highly saturated copolymer rubber exhibits a high-rate vulcanizability when vulcanized with a sulfur-containing vulcanizer.

    摘要: A nitrile group-containing rubber latex comprising an aqueous dispersion of a nitrile group-containing highly saturated rubber having an iodine value of not more than 120. The said rubber latex can be produced by converting a solution of a nitrile group-containing highly saturated polymer rubber having an iodine value of not more than 120 in an inert solvent into an oil-in-water emulsion using water and an emulsifier, and removing the solvent from the resulting emulsion.

The covering rubber layer is a vulcanized rubber layer formed by a rubber composition comprising an ethylenically unsaturated nitrile-conjugated diene type highly saturated copolymer rubber (A) having a conjugated diene unit content of the polymer chain of at most 25 wt. % and the zinc salt (B) of an ethylenically unsaturated carboxylic acid. A covering rubber layer coming into contact with the metallic core is at least a vulcanized rubber layer formed by a rubber composition comprising 100 parts by weight of a rubber component containing at least 50 wt. % of the highly saturated copolymer rubber (A) and 10-40 parts by weight of the zinc salt (B). A rubber composition for rubber covered rolls is also disclosed. It comprises 100 parts by weight of a rubber component containing 90-50 wt. % of the highly saturated copolymer rubber (A) and 50-10 wt. % of a diene rubber, and 10-40 parts by weight of the zinc salt (B) of an ethylenically unsaturated carboxylic acid.
