(57) [Summary] [PROBLEMS] A rubber composition, a crosslinkable rubber composition, and a crosslinked product thereof, which are more excellent in heat resistance of a crosslinked product than a conventional acrylic rubber composition, and in particular, have a small change in elongation due to heat load I will provide a. SOLUTION: An acrylic rubber composition is obtained by blending an aromatic secondary amine compound (b) and nickel dialkyldithiocarbamate (c) with an acrylic rubber (a). A crosslinkable rubber composition is obtained by blending a crosslinker with the acrylic rubber, and the crosslinkable rubber composition is crosslinked to obtain a crosslinked product. |
