Procedure

75 parts by weight of styrene, 25 parts by weight of acrylonitrile, and 120 parts by weight of deionized water are mixed. 0.2 parts by weight of azobisisobutylonitrile (AIBN), 0.4 parts by weight of tricalciumphosphate and 0.2 parts by weight of mercaptan-containing chain transfer agent are added into the mixture. The resultant solution is heated from room temperature to 80° C. for 90 minutes and then kept for 180 minutes at this temperature to obtain a styrene-acrylonitrile copolymer resin (SAN). The styrene-acrylonitrile copolymer resin (SAN) is washed, dehydrated and dried to obtain a styrene-acrylonitrile copolymer resin (SAN) in a powder form. The prepared styrene-acrylonitrile copolymer resin (SAN) has a weight average molecular weight (Mw) of about 90,000 g/mol.
