Versuchsvorschrift

Nine hundred and fifty parts by mass of a butadiene monomer, 50 parts by mass of styrene, 135 parts by mass of deionized water (the concentration of iron: less than 0.02 ppm), 3.0 parts by mass of potassium oleate, 0.3 parts by mass of potassium persulfate, 0.2 parts by mass of tertiary dodecyl mercaptan, and 0.18 parts by mass of potassium hydroxide were placed in a pressure-resistant container with a stirrer. The temperature was raised to 60° C., and polymerization was started. The polymerization was performed for 15 hours to obtain a styrene butadiene rubber latex having a volume average particle size of 80 nm measured by a Microtrack particle size analyzer “nanotrac 150” (trade name) made by NIKKISO CO., LTD. and a solid content of 40% by mass.
