Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a production method for an acrylic rubber composition having a low adhesive force and excellent workability, excellent in a low-temperature characteristic and a low swelling property against a lubricant such as a grease, having a sufficient mechanical strength, and excellent in elasticity. SOLUTION: This production method for the acrylic rubber composition includes a process for obtaining a polymerization liquid by polymerizing a monomer component containing an acrylate and a crosslinking point monomer, in a solvent containing a laminar clay mineral, and a process for salting out the polymerization liquid, and uses, as the acrylate, an acrylate containing 60 mass% or more of at least one kind of acrylate selected from the group comprising butyl acrylate and methoxy ethyl acrylate.
