A process for producing a thermoplastic resin which comprises graft-polymerizing at least one vinyl monomer (IV) onto a modified polyorganosiloxane (III) obtained by condensation of from 90 to 99.8% by weight of an organosiloxane (I) having a structural unit represented by the formula R.sup.1.sub.n SiO.sub.(4-n)/2, wherein R.sup.1 represents a substituted or unsubstituted monovalent hydrocarbon group and n is an integer of from 0 to 3, and from 10 to 0.2% by weight of a graft crosslinking agent (II) having a modified alkoxysilane structure.

Process for producing thermoplastic resin

An organosilicon compound represented by the general formula: ##STR1## where R.sup.1 represents a substituted or non-substituted monovalent hydrocarbon group, X represents a chloromethyl group, (meth)acryloxymethyl group, glycidoxymethyl group or aminomethyl group, Y represents a hydrolyzable group or hydroxyl group, n represents a number of 1, 2 or 3. The compound is useful, for example, for the improvement of adhesion between the organic and inorganic materials.
