Procedure

100 Parts of a mixture of styrene monomer and acrylonitrile monomer in a weight proportion of 70:30 and in which a peroxide catalyst, a molecular weight-regulating agent, etc. had been dissolved in a conventional manner and 100 parts of water containing a Ca-salt as a dispersion stabilizer were placed in a suspension polymerization vessel and suspension polymerization was effected. After termination of the polymerization, there was obtained an acrylonitrile/styrene copolymer in the form of an aqueous slurry having a particle diameter in the range of 100 to 1000μ and a residual monomer content in the range of 1 to 5 wt.%.
