実験手順

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