Abstract
Disclosed is a method for producing a nitrile rubber comprising adding 0.1 to 5 parts by weight of at least one phosphate emulsifier selected from the group consisting of monoalkyl ether phosphate (MAP) represented by the following Formula 1 and dialkyl ether phosphate (DAP) represented by the following Formula 2, with respect to 100 parts by weight of monomers constituting the nitrile rubber. The method minimizes mold contamination during molding of produced nitrile rubber, eliminates the necessity of any process of removing mold contaminants, improves production efficiency and thus reduces defect rates of final molded articles.
