A thermoplastic resin containing a graft copolymer obtained by graft-copolymerizing at least one vinyl monomer onto colloidal silica-core silicone-shell particles, and a process for producing the thermoplastic resin. n A colloidal silica-core silicone-shell particles comprisingn (A) from 99.9 to 5% by weight of cores which are colloidal silica particles, and (B) from 0.1 to 95% by weight of shells comprising an organosiloxy group represented by the formula n n wherein R¹ which may be the same or different each represents a substituted or unsubstituted monovalent hydrocarbon group having 1 to 8 carbon atoms, Q represents hydrogen atom or an alkyl group having 1 to 6 carbon atoms, p is an integer of 1 to 3, and q is an integer of 0 to 2, with proviso that (p+q) is an integer of 1 to 3, nand/or a polyorganosiloxane represented by the average composition formulan n wherein R² which may be the same or different each represents a substituted or unsubstituted monovalent hydrocarbon group having 1 to 8 carbon atoms and a is a number of 0.8 to 3.0, wherein 0.02 to 100 mole% of the sum of R¹ and R² are groups containing a reactive unsaturated group. |
