Abstract
A continuous production method of polyorganosiloxane particles by press-introducing an organoalkoxysilane into an aqueous phase such as water through a porous membrane to form a monodisperse O/W type emulsion and adding a catalyst to the emulsion to condensation polymerize the organoalkoxysilane. Non-porous polyorganosiloxane particles having a uniform particle size can be stably and continuously produced with a high efficiency.
