Abstract
A crosslinkable rubber composition, comprising: an acrylic rubber; an amine compound represented by the following formula (A-1); a carbon black; and a crosslinking agent, wherein the acrylic rubber has acrylate units and carboxy group-containing monomer units, and has 0.5 to 10 parts by mass of ethylene units with respect to 100 parts by mass of the acrylate units and/or 5 to 20 parts by mass of alkyl methacrylate units with respect to 100 parts by mass of the acrylate units, wherein R1 represents a hydrogen atom or an amino group in the formula (A-1).

A crosslinkable rubber composition, comprising:
- an acrylic rubber;
- an amine compound represented by the following formula (A-1);
- a carbon black;
- and a crosslinking agent, wherein
- the acrylic rubber has acrylate units and carboxy group-containing monomer units, and has 0.5 to 10 parts by mass of ethylene units with respect to 100 parts by mass of the acrylate units and/or 5 to 20 parts by mass of alkyl methacrylate units with respect to 100 parts by mass of the acrylate units,
- wherein R1 represents a hydrogen atom or an amino group in the formula (A-1).
An acrylic rubber, comprising
- acrylate units,
- carboxy group-containing monomer units,
- amine-containing monomer units having a group represented by the following formula (B-1), and
- ethylene units at 0.5 to 10 parts by mass with respect to 100 parts by mass of the acrylate units and/or alkyl methacrylate units at 5 to 20 parts by mass with respect to 100 parts by mass of the acrylate units,
- wherein R1 represents a hydrogen atom or an amino group in the formula (B-1).
