(57) [Abstract] [Purpose] To obtain a granulated composition based on a peroxide derivative, which does not cause nonuniform composition or generation of dust during handling. As a granulating agent, two binders, namely polyvinyl alcohol, a first binder selected from the group consisting of homopolymers and copolymers of vinylpyrrolidone, and mixtures thereof, and an alkylene group C 2 to C 4 , A second selected from the group consisting of polyalkylene glycols having a molecular weight of 200 to 30,000 and mixtures thereof. And the binder is used, and the particle size of the granules is 65 to 800 μm. |
