摘要

100 parts by mass of an acrylic acid alkyl ester having an alkyl group having 1 to 3 carbon atoms, 20 to 160 parts by mass of an acrylic acid alkyl ester having an alkyl group having 4 to 8 carbon atoms, and a crosslinked seat monomer containing a carboxyl group 0. A method for producing acrylic rubber, in which 80 to 100% by mass of the total mass of the monomer component containing 1 to 10 parts by mass is added and emulsion polymerization is carried out at a polymerization temperature of 20 to 60 ° C. The monomer component may further contain an alkyl methacrylate ester having an alkyl group having 1 to 4 carbon atoms and ethylene.
