Reaction Steps

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, 0.6 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 as a polymerization initiator, and a very small amount of redox assistants such as iron, Rongalite (a trademark for sodium formaldehyde sulfoxylate) and so on, and the emulsion-polymerization was conducted at a temperature of 45°C for 16 hours to obtain a rubber latex of butadiene-styrene copolymer.
