  • Cross-linkable nitrile rubber composition and cross-linked rubber
    Patent number: 8034881
    Abstract: A cross-linkable nitrile rubber composition containing a highly saturated nitrile rubber (a) having an ?,?-ethylenically unsaturated nitrile monomer unit and a carboxyl-group containing monomer unit and having an iodine value of 120 or less, a cross-linking agent (b), and a specific cyclic amidine and/or cyclic amidinium salt (c) is provided. Preferably, the cross-linking agent (b) is a polyamine-based cross-linking agent (d), and more preferably, the carboxyl-group containing monomer unit is an ?,?-ethylenically unsaturated dicarboxylic acid monoester monomer unit.
    Type: Grant
