反応手順
Into a stainless steel autoclave of 10-liter capacity having an agitator, there were charged 48 parts by weight of butadiene, 12 parts by weight of styrene, 0.2 part by weight of divinyl benzene, and 200 parts by weight of water containing therein 0.9 part by weight of potassium oleate as an emulsifier, 0.12 part by weight of diisopropyl benzene hydroperoxide, and a very small amount of redox assistants such as Rongalite (a trademark for sodium formaldehyde sulfoxylate), iron, and so forth, after which the emulsion-polymerization was conducted at a temperature of 45°C for 17 hours to obtain a rubber latex of butadiene-styrene copolymer.
