Abstract

See full text

To obtain a sugar-plum shaped composite particle, a reaction vessel with 300 parts by weight of water placed therein is charged with 30 parts by weight of polymethyl methacraylate resin particles of 2 μm average particle diameter, and ultrasonic waves are applied to the mixture for 1 minute to obtain a particle dispersion liquid. Subsequently, 15 parts by weight of methyltrimethoxysilane is added to the dispersion liquid to obtain methyltrimethoxysilane hydrolyzates in the dispersion liquid. Thereafter, 10 parts by weight of 1 weight % aqueous ammonia is added thereto and agitated. One minute later, the agitation is discontinued, and the mixture is allowed to stand still for 10 hours to effect maturation. The resultant mixture is filtered and dried to obtain sugar-plum-shaped particles provided on their surfaces with polyorganosiloxane projections.
