Abstract
Spherical gel particles with elastomeric surfaces are made by dripping a liquid silicone gel composition containing alkenyl-containing organopolysiloxane, organohydrogenpolysiloxane, and a platinum catalyst into water or surfactant-containing water, curing and then contacting the surface of the silicone gel particles to organohydrogenpolysiloxane and curing to provide the elastomeric surface. The liquid silicone gel composition can also be extruded in fiber form into the water or surfactant-containing water with stirring to form the spherical particles which are cured and then the surface is contacted with organohydrogenpolysiloxane forming the silicone gel particles with elastomer surface. Alternatively, the liuqid silicone gel composition can be dripped or extruded in fiber form into a liquid having organohydrogenpolysiloxane to form the silicone gel particles with elastomer surface when the particles are cured. These spherical silicone gel particles are uniform and can be used to modify organic resins and be used for vibration absorption.
