Procedure

After the liquid temperature of the latex lowered to 60° C., a mixed solution of 10 parts of acrylonitrile, 23.3 parts of styrene and 0.1 part of cumene hydroperoxide was added dropwise thereto over 2 hours to carry out polymerization. After the finish of dropping, the temperature of 60° C. was kept for 1 hour, and then a mixed solution of 10 parts of acrylonitrile, 23.3 parts of styrene, 0.03 part of n-octylmercaptan and 0.1 part of cumene hydroperoxide was again added dropwise thereto over 2 hours to carry out polymerization. After the finish of dropping, the temperature of 60° C. was kept for 2 hours, and then the reaction solution was cooled to obtain the latex of a graft compound rubber in which an acrylonitrile/styrene copolymer had been graft-polymerized onto a compound rubber comprising polydimethylsiloxane and polybutyl acrylate.
