(57) Abstract: [configuration] or the [R 1 SiO 3/2] a structural unit, or [R 1 SiO 3/2] and [R 2 2 SiO] and / or a [SiO 2] Configuration In units, the average composition formula is R 1 j R 2 k SiO l (R 1 and R 2 each represent a group selected from the group consisting of an alkyl group having 1 to 4 carbon atoms, an alkenyl group having 2 to 4 carbon atoms, and a phenyl group, and j and k are 0 to 1.4, j + k is 0.6 to 1.4, and l is 1. It is a number from 3 to 1.7, and 2l + j + k = 4. ) Is dissolved in an aqueous solution of an alkali hydroxide, cations are removed by an ion exchange method, and the resulting solution is gelled at a temperature of 50 ° C or higher and a pH of 10 or higher. A method for producing spherical silicone fine particles of 0.1 to 20 μm. [Effect] Spherical silicone fine particles having a narrow particle size distribution can be produced by using a hydrocarbon group-substituted organopolysiloxane, which is an inexpensive raw material. |
