Abstract: The present invention aims to provide an acrylic copolymer capable of maintaining excellent storage stability in the uncrosslinked state even after long-term exposure to high temperatures, and a crosslinked acrylic rubber product produced from the acrylic copolymer which maintains good normal-state properties and good water resistance. The present invention is based on the finding that an acrylic copolymer produced by polymerizing a liquid mixture of an alkoxyalkyl (meth)acrylate containing an alkoxyalkyl group and a crosslinkable monomer containing a carboxy group has excellent storage stability and that a crosslinked product produced from the acrylic copolymer has good normal-state properties and good water resistance.
