Procedure

Eighty-seven parts of styrene, 13 parts of acrylonitrile, 120 parts of deionized water, 0. 1 parts of azobisisobutylonitrile, 0.2 parts of 1,1′-di(tertiarybutylperoxy)-3,3′, 5-trimethylcyclohexane, 0.4 parts of tricalcium phosphate and 0.2 parts of mercaptan-containing chain transfer agent were blended. The resulting solution was heated up to 80° C. for 90 minutes and was kept at 80° C. for 150 minutes. The solution was heated up to 95° C. again and kept for 120 minutes. The resultant was washed, dehydrated and dried. Styrene-acrylonitrile copolymer (SAN) having a weight average molecular weight from 100,000 to 140,000 and 13% by weight of acrylonitrile content was obtained.
