ACRYLIC RUBBER COMPOSITION AND CROSSLINKED PRODUCT

摘要

An acrylic rubber composition which comprises a carboxyl group-containing acrylic rubber containing 0.1 to 30 wt % of a structural unit derived from methacrylonitrile (A) in an amount of 100 parts by weight, and a polyvalent amine crosslinking agent (B) and a monoamine compound (C) in an amount of 0.05 to 20 parts by weight, respectively. The acrylic rubber composition is free from the adhesion to a metalic material during kneading and is excellent in the resistance to scorching during being processed, and further can provide a crosslinked product excellent in the resistance to heat, a low temperaure atmosphere and the deterioration by an oil.
