Abstract
One aspect of the invention relates to a method of preparing silicone fine particles which comprises preparing a mixture comprising an organotrialkoxysilane and an organochlorosilane to give a concentration of the organochlorosilane in the mixture of about 100 to about 2,000 ppm; mixing the mixture with water to prepare a sol solution; and maintaining a pH value of the sol solution within a range of about 8 to about 11. Another aspect of the invention relates to a thermoplastic resin composition which employs the silicone fine particles as a diffuser.
