Procedure

An amount of 1155 g of an aqueous latex of a core polymer mainly comprising a styrene-butadiene rubber (containing 375 g of styrene-butadiene rubber particles) as obtained using the procedure described in Example 2 was charged into a 3 L glass vessel followed by addition of 440 g of pure water. A monomer mixture composed of 62 g of methyl methacrylate, 38 g of styrene and 0.1 g of t-butyl hydroperoxide as a monomer mixture that is not the shell forming monomers (A) was added thereto over the course of 120 minutes while stirring at 60° C. in a nitrogen atmosphere to carry out graft polymerization. Following completion of the addition of the monomer mixture, stirring was further continued for 2 hours to complete the reaction. The polymerization conversion rate was 99%. The volume average particle size of the resulting minute polymer particles (CS-1C) in the form of an aqueous latex was 0.1 μm, and a sharp, monodisperse particle size distribution similar to CS-2 of Example 2 was shown.
