Versuchsvorschrift

A stainless-steel-made reactor equipped with a stirrer was charged with 70 parts of styrene, 30 parts of acrylonitrile, 1.0 part of calcium phosphate, 0.03 part of GAFAC GB520 (brand name, dispersion aid, manufactured by Toho Chemical Co., Ltd.), 0.6 part of lauryl peroxide, 1.0 part of t-dodecylmercaptan and 200 parts of ion-exchanged water to carry out polymerization for 6 hours after elevating the temperature up to 80° C., whereby a copolymer having an intrinsic viscosity of 0.6 dl/g (20° C. in N,N′-dimethylformamide) was obtained at a conversion rate of 98%.
