Beschreibung
Zusammenfassung:	An acrylic rubber comprised of a copolymer comprising 0.1 to 20% by weight of (A) units of a butenedioic acid monoester monomer having an alicyclic structure and 50 to 99.9% by weight of (B) units of at least one kind of monomer selected from acrylic acid ester monomers and methacrylic acid ester monomers. A crosslinkable acrylic rubber composition comprising the acrylic rubber and a crosslinking agent, especially a polyamine crosslinking agent, has good process-stability and good shapability and gives a shaped article having high heat resistance and exhibiting reduced permanent set.
