摘要： PURPOSE:To facilitate the formation of the title particle excellent in abrasion resistance, water repellency and lubricity by forming a surface part comprising perfluoro-alkylenesilsesquioxane units around a core comprising polymethylsilsesquioxane units. CONSTITUTION:Methyltrialkoxysilane or its partial hydrolyzate is hydrolyzed in an aqueous alkali solution to form a core comprising polymethylsilsesquioxane units. A perfluoroalkyl-trialkoxysilane is added to the aqueous medium in which the cores are dispersed and hydrolyzed. In this way, a surface part comprising perfluoroalkylsilsesquioxane units is formed around the cores to obtain polyorganosilsesquioxane particles. When combined with a water repellent, an oil repellent or the like, the obtained particles can be used as a nonadhesive coating material, a cosmetic material, an additive to a polishing agent or the like.
