<P>PROBLEM TO BE SOLVED: To provide a crosslinkable rubber composition that provides a crosslinked material with small compression set while well-maintaining a variety of properties such as mechanical strength, and to provide a crosslinked rubber material obtained by crosslinking the rubber composition. <P>SOLUTION: A crosslinkable rubber composition comprises: 0.1 to 20 pts.wt of a primary monoamine having no polar group other than an amino group; and 0.1 to 20 pts.wt of a polyamine-based crosslinking agent, based on 100 pts.wt 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 an iodine value of 120 or less. <P>COPYRIGHT: (C)2013,JPO&INPIT |
