Procedure

72 parts of styrene, 28 parts of acrylonitrile, and 120 parts of deionized water are mixed. To the mixture, 0.2 parts of azobisisobutylonitrile (AIBN), 0.4 parts of tricalcium phosphate 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 180 minutes. The resultant is washed, dehydrated and dried to obtain styrene-acrylonitrile copolymer resin (SAN) in powder form.
