Abstract

To provide a method for producing composite particles with a high polymerization rate, i.e., high manufacturing efficiency. [Solution] The process of graft polymerization of monomers in the presence of inorganic particles to which polymerization initiators are attached is suspension polymerization, and the energy dissipation rate in the emulsification step in the suspension polymerization is 1.0 × 10 8 A method for producing composite particles having polymer graft chains with a concentration of less than [W / kg].
