Procedure

Separately, a nitrogen-atmosphered reactor was charged with 120 parts of water and 0.3 part of potassium persulfate, and after heating the contents to 65° C., a mixture comprising 70 parts of styrene, 30 parts of acrylonitrile, 0.3 part of t-dodecylmercaptan and 1.5 parts of an aqueous 10% potassium oleate solution was added thereto continuously over 4 hours, followed by polymerization for further 2 hours at 65° C. to obtain a styrene-acrylonitrile copolymer.

Workup

  1. customfollowed by polymerization for further 2 hours at 65° C.
