The present invention relates to an acrylic copolymer, an acrylic-copolymer-containing composition, and a crosslinked object obtained therefrom. More specifically, the present invention relates to a crosslinked object retaining satisfactory elongation at break even when exposed to high temperatures over a long period. A crosslinked object obtained by crosslinking an acrylic copolymer obtained by polymerizing a liquid mixture comprising an alkyl acrylate, which has an alkyl group, an alkyl methacrylate, and a crosslinking monomer was found to have satisfactory elongation at break even when exposed to high temperatures over a long period. |
