Abstract
A method for preparing silicone particles having an average particle size of 6 microns or less, said method comprising the following steps. First, a multifinctional vinyl terminated polysiloxane is mixed with a hydride terminated polysiloxane, surfactant, and polymerization catalyst under ambient conditions. This mixture is then dispersed in water under ambient conditions. The dispersion is the heated to cure the silicone. Afterwards the dispersion is broken and the particles are washed.
