Procedure

Distilled water in an amount of 115 parts by mass, 1 part by mass of calcium tertiary phosphate, and 0.001 parts by mass of DEMOL P (produced by Kao Corp.) were placed in a reaction vessel and stirred. A mixture of 25 parts by mass of acrylonitrile, 75 parts by mass of styrene, 0.5 parts by mass of t-dodecylmercaptan, 0.17 parts by mass of azobisisobutyronitrile, and 0.003 parts by mass of GAFAC GB-520 (produced by Toho Chemical Industry Co., Ltd.) was added to the reaction vessel to make them a state of suspension, heated up to 75° C., and maintained at the same temperature for 240 minutes to complete the polymerization thereby to obtain acrylonitrile-styrene copolymer resin (x-1). The resin (x-1) thus obtained had a chemical composition of acrylonitrile/styrene=34/66 (mass ratio).
