Abstract
There is provided a method for more easily producing an acrylic rubber capable of providing a crosslinked rubber having excellent water resistance. A method for producing an acrylic rubber comprising the steps of subjecting a monomer to emulsion polymerization to obtain a polymerized emulsion; mixing the polymerized emulsion with a coagulant to obtain a water-containing crumb; and water-washing the water-containing crumb, wherein, in the step of water-washing the water-containing crumb, the water-containing crumb is water-washed until an electrical conductivity of the washing water after water-washing the water-containing crumb becomes 6.0 mS/cm or less.
