実験手順

75 parts of styrene, 25 parts of acrylonitrile, 120 parts of deionized water and 0.2 parts of azobisisobutylonitrile were blended. To the blend, 0.4 parts of tricalciumphosphate and 0.2 parts of mercaptan-containing chain transfer agent were added. The resultant solution was heated to 80° C. for 90 minutes and kept for 180 minutes. The resultant was washed, dehydrated and dried to produce SAN powder. styrene-acrylonitrile copolymer (SAN) having a weight average molecular weight of 160,000 to 200,000 was obtained.
