Abstract

The finely divided cured silicone rubber particles of the present invention contain at least epoxide compound or a condensation product thereof. The epoxide compound or a condensation product thereof can be present in the free state or chemically bonded to the silicone rubber, and the particles have a particle diameter of 1 mm or less. The particles exhibit excellent compatibility with a variety of materials, including various organic resins and synthetic rubbers, and when added to or admixed with these materials enhance the physical properties of these materials and are durably bonded within matrices of these materials.
