Versuchsvorschrift

72 parts of styrene, 28 parts of acrylonitrile, 120 parts of deionized water and 0.2 parts of azobisisobutylonitrile (AIBN) are mixed. To the mixture, 0.4 parts of tricalciumphosphate and 0.2 parts of mercaptan-containing chain transfer agent are added. The resultant solution is heated to 80° C. for 90 minutes and kept for 240 minutes. The resultant is washed, dehydrated and dried to obtain styrene-acrylonitrile copolymer resin (SAN) in powder form. The weight average molecular weight of the SAN copolymer resin is 180,000 to 200,000.
