Versuchsvorschrift

In a reactor which had been replaced with nitrogen, pure water (150 parts), potassium persulfate (0.5 part) and sodium laurylsulfate (2 parts) were charged and heated to 70° C. while stirring. Then, a mixed monomer solution of acrylonitrile (30 parts), α-methylstyrene (70 parts) and tert.-dodecylmercaptan (0.2 part) was continuously added over 5 hours. The polymerization system was heated to 75° C. and aged for 5 hours to complete the polymerization to obtain a latex of acrylonitrile-α-methylstyrene copolymer.
