Abstract:
1. A process for producing the sugar-plum-shaped particles, wherein the process consists of dispersing 10 to 100 parts by weight of an organotrialkoxysilane and/or an organotrialkoxysilane hydrolysate and 100 parts by weight of organic resin particles in water to form a reaction solution, then, before the organotrialkoxysilane and/or an organotrialkoxysilane hydrolysate undergoes a dehydration condensation reaction, adjusting the pH of the reaction solution to 8.0 to 10.5 by adding an alkaline substance or an alkaline aqueous solution to the reaction solution, and then precipitating particles having polyorganosiloxane projections on surfaces of the organic resin particles.
