The present invention provides silicone polymer particles having excellent tensile properties and excellent transparency and also provides a silicone composition. The present invention relates to silicone polymer particles having a silicone core-alkoxysilane condensate shell structure in which silicone particles with a volume-average particle diameter of 0.001 μm to 1.0 μm are coated with an alkoxysilane condensate, and also relates to a silicone composition containing (A) the silicone polymer particles, (B) a polyorganosiloxane having at least one alkenyl group in its molecule, and (C) a curing agent. The present invention further relates to respective manufacturing methods of the silicone polymer particles and the silicone composition.
A silicone composition comprising
A method of manufacturing a silicone polymer particle having a silicone core-alkoxysilane condensate shell structure comprising a silicone particle with a volume-average particle diameter of 0.001 to 1.0 μm, wherein the silicone particle substantially consists of a polyorganosiloxane, and is directly coated with an alkoxysilane condensate, the method comprising coating a silicone particle produced by emulsion polymerization with an alkoxysilane condensate by condensation reaction of alkoxysilane.
