Procedure
An amount of 1300 g of an aqueous latex of a core polymer mainly comprising a styrene-butadiene rubber (containing 420 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 and stirring at 70° C. while replacing the atmosphere inside the vessel with nitrogen. A monomer mixture composed of 60 g of methyl methacrylate, 10 g of butyl acrylate, 35 g of styrene and 0.4 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 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 and obtain minute polymer particles (CS-2C) in the form of an aqueous latex. The polymerization conversion rate was 99%. As a result of measuring the particle size in the same manner as in Example 2 after diluting the minute polymer particles in the form of an aqueous latex with water, the measured particle size was 0.1 μm, and a sharp, monodisperse particle size distribution nearly similar to that of Example 2 was shown.
