摘要：
A process for producing a polyorganosiloxane-based thermoplastic resin which comprises graft polymerizing (3) at least one vinyl monomer using (4) an initiator which is an organic peroxide which, upon decomposition, produces an organic radical represented by the structural formula: ##STR1## wherein R.sup.2, R.sup.3 and R.sup.4 represent independently hydrogen atoms or alkyl groups having 1 to 10 carbon atoms, in the presence of (2) a polyorganosiloxane.
