ABSTRACT:
An acrylic rubber composition comprising a carboxyl group-containing acrylic rubber (A) comprising 0.1 to 30% by weight of structural units derived from methacrylonitrile, and a polyamine crosslinking agent (B) and a monoamine compound (C); wherein the amount of each of the crosslinking agents (B) and the monoamine compound (C) is in the range of 0.05 to 20 parts by weight based on 100 parts by weight of the acrylic rubber (A). This acrylic rubber composition is free from sticking to a metal at kneading and exhibits good resistance to scorch during being processed, and gives a crosslinked product having good heat resistance, good cold resistance and good resistance to deteriorated oil.
