Styrene → Prop-2-enenitrile--ethenylbenzene (1/1)

Participants

Reaction Conditions

Reaction Steps

In a reactor which had been replaced with nitrogen, potassium persulfate (0.3 part) and pure water (120 parts) were charged and heated to 65° C. while stirring. Then, a mixed monomer solution of acrylonitrile (30 parts), styrene (70 parts) and tert.-dodecylmercaptan (0.3 part) and an aqueous solution of emulsifier (30 parts) containing disproportionated potassium resinate (2 parts) were continuously added over 4 hours each. The polymerization system was heated to 70° C. and aged for 3 hours to complete the polymerization to obtain a latex of acrylonitrile-styrene copolymer.
