ABSTRACT:
An acrylic rubber, comprising an alkoxyalkyl(meth)acrylate monomer unit in an amount of 70.1 to 99.8 wt %, a methacrylonitrile monomer unit in an amount of 0.1 to 9.9 wt % and a butenedionic acid monoester monomer unit in an amount of 0.1 to 20 wt %; and a cross-linkable acrylic rubber composition made by containing the acrylic rubber and a cross-linking agent. According to the invention, it is possible to provide a cross-linkable acrylic rubber composition having excellent scorch stability and an acrylic rubber cross-linked product, which can be obtained by cross-linking the cross-linkable acrylic rubber composition, having excellent heat resistance, cold resistance and fuel oil resistance.
