Abstract

The present invention relates to a method for producing a composite particle having a polymer graft chain including; (Step 1) reacting an inorganic particle with a silane compound having a polymerization initiation group other than a halosulfonyl group to bind the polymerization initiation group to the inorganic particle, and (Step 2) subjecting a monomer to a graft polymerization in the presence of the inorganic particle bound with the polymerization initiation group, wherein Step 1 is carried out in a powder state. According to the present invention, a composite particle having a graft density equivalent to a conventional method using a solvent at the time of introducing a polymerization initiation group can be obtained, and a method for production having excellent handling property at the time of production is provided.
