Versuchsvorschrift

After the solution temperature inside the reactor vessel decreased to 60° C., an aqueous solution having 0.4 parts of rongalit dissolved in 10 parts of distilled water was added. Next, a mixed solution including 11.1 parts of acrylonitrile, 33.2 parts of styrene, and 0.2 parts of tertiary butyl hydroperoxide was added dropwise over about 1 hour to effect polymerization. After the dropwise addition, the solution was allowed to stand for 1 hour, and then was added with an aqueous solution having 0.0002 parts of ferrous sulfate, 0.0006 parts of disodium ethylenediaminetetraacetate, and 0.25 parts of rongalit dissolved in 10 parts of distilled water. Next, a mixed solution including 7.4 parts of acrylonitrile, 22.2 parts of styrene, and 0.1 part of tertiary butyl hydroperoxide was added dropwise over about 40 minutes to effect polymerization. After the dropwise addition, the solution was allowed to stand for 1 hour, and then was cooled down, thereby yielding a graft copolymer latex in which an acrylonitrile-styrene copolymer was grafted to the composite rubber consisting of polyorganosiloxane and the butyl acrylate rubber.
