Abstract
An acrylic rubber composition comprising (A) 100 parts by weight of an acrylic rubber comprising (a) 90 to 99.9% by weight of acrylic acid ester monomer units, (b) 0.1 to 10% by weight of carboxyl group-containing ethylenically unsaturated monomer units, and (c) 0 to 20% by weight of other copolymerizable monomer units, (B) 0.05 to 2.5 parts by weight of a primary monoamine compound, and (C) 0.05 to 5 parts by weight of a polyamine vulcanizer. The rubber composition gives a vulcanizate which is used as sealing material, hose material, vibration insulator material, tube material, belt material and boot material.
