Procedure

75 parts of styrene, 25 parts of acrylonitrile, and 120 parts of deionized water are mixed. To the mixture, 0.2 parts of azobisisobutylonitrile (AIBN), 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 180 minutes. The resultant product is washed, dehydrated and dried to obtain styrene-acrylonitrile copolymer (SAN) in a powder form. The styrene-acrylonitrile copolymer (SAN) has a weight average molecular weight (Mw) of about 80,000 to about 100,000.
