It is an object of the present invention to provide an acrylic copolymer for providing a highly heat-resistant rubber material that shows a small rate of change in strength without loss of elongation, even under a high-temperature condition over a long period, and a composition containing the acrylic copolymer. The present invention provides an acrylic copolymer comprising a structural unit (A) derived from a monomer containing a structure having a maleimide skeleton, a structural unit (B) derived from an acrylic acid alkyl ester and/or a structural unit (B) derived from an acrylic acid alkoxyalkyl ester, and a structural unit (C) derived from an unsaturated monomer having a crosslinking group; a composition comprising the acrylic copolymer and a crosslinking group; and a rubber material produced from the composition.

Acrylic copolymer and rubber material

A semiconducting component for an electrographic device, comprising a crosslinked body obtained by crosslinking a copolymer containing 9.9 to 39.9% by mole of structural units (a) originating from an epihalohydrin, 60 to 90% by mole of structural units (b) originating from an alkylene oxide, and 0.1 to 10% by mole of structural units (c) originating from a cyclic ether monomer having a (meth)acryloyl or alkoxysilyl group with use of reactivity of the structural units originating from the cyclic ether monomer having a (meth)acryloyl or alkoxysilyl group.
