실험 절차

76 parts by weight of styrene, 24 parts by weight of acrylonitrile, and 120 parts of deionized water are mixed. To the mixture, 0.17 parts by weight of azobisisobutylonitrile (AIBN), 0.4 parts by weight of t-dodecyl mercaptan chain transfer agent, and 0.5 parts by weight of tricalciumphosphate are added. The mixture is suspension polymerized at 75° C. for 5 hours, and a styrene-acrylonitrile (SAN) copolymer resin is obtained. The resultant copolymer is washed, dehydrated and dried to obtain SAN copolymer resin having a weight average molecular weight of 150,000 g/mol in powder form.
