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.

Abstract: Separation of a mixture of plastic materials by separating the plastic mixture according to particle size, and introducing plastic of similar size particles into a vertical fluidized bed column having an upwardly flowing gaseous stream therein. The flow rate of the gaseous stream is controlled to provide a relatively low density fraction of the plastic mixture exiting at the upper end of the column, and a relatively high density fraction of the plastic mixture exiting at the lower end of the column. In one embodiment, electrostatic charges are induced on the particles of the plastic mixture prior to introducing the plastic of similar size particles into the column, and the column is charged to attract thereto the plastic particles having the highest electrostatic charge.
