    • 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.
    • 作为通过使不饱和腈共轭二烯共聚物的共轭二烯部分氢化得到的产物的含腈基高饱和共聚物橡胶。 高度饱和的共聚物橡胶具有碳原子数为12〜16的烷硫基,其包含至少三个叔碳原子,并且具有与叔碳原子中的至少一个直接结合的硫原子,高饱和共聚物橡胶 进一步具有15至200的门尼粘度和不大于80的碘值。通过使用具有12个碳原子的烷基硫醇化合物作为分子量调节剂,制备高度饱和的共聚物橡胶,使不饱和腈,共轭二烯和任选的可共聚单体共聚 至少16个碳原子,其包括至少三个叔碳原子,并且具有与至少一个叔碳原子直接结合的硫原子; 然后氢化由此得到的共聚物。 当用含硫硫化剂硫化时,高度饱和的共聚物橡胶表现出高速硫化性。
