Method for producing polyorganosiloxane particles and for producing silica particles |
摘要 |
The present invention provides a method for producing polyorganosiloxane particles through the step of hydrolyzing and condensing a silicon compound having a non-hydrolyzable group and a hydrolyzable alkoxyl group bonded to its silicon atom in the presence of a catalyst and thereby forming seed particles of polyorganosiloxane particles to obtain a seed-particles-containing solution and the step of adding a particle-diameter-growing aqueous solution containing the same silicon compound or a hydrolyzate thereof to the above seed-particles-containing solution to grow the above seed particles, the method comprising the step of obtaining the seed-particles-containing solution, in which particles are measured for a particle diameter continuously or at intervals of a constant time period and terminating the reaction at a time when an intended-particle diameter is reached.
