Procedure

71 parts of styrene, 29 parts of acrylonitrile, 120 parts of deionized water and 0.17 parts of azobisisobutylonitrile (AIBN) are mixed. To the blend, 0.4 parts of t-dodecyl mercaptan chain transfer agent and 0.5 parts of tricalciumphosphate are added. The mixture is suspension polymerized at 75° C. for 5 hours. The resultant composition is washed, dehydrated and dried to obtain styrene-acrylonitrile copolymer (SAN) in powder state.
