Versuchsvorschrift

Seventy (70) parts by mass of styrene, 30 parts by mass of acrylonitrile, 1.0 part by mass of calcium phosphate, 0.03 part by mass of “GAFAC GB520” (trade name, dispersing agent, TOHO Chemical Industry Co.,Ltd.), 0.6 part by mass of laurylperoxide, 1.0 part by mass of t-dodecylmercaptan, and 200 parts by mass of ion-exchanged water were charged in a stainless steel reactor equipped with an agitator. The temperature was elevated to 80° C. and polymerization was carried out for 6 hours to obtain a copolymer having an intrinsic viscosity of 0.6 dl/g (at 20° C. in N,N′-dimethylformamide) with 98% conversion.
