Reaction Steps
75 parts by weight of styrene, 25 parts by weight of acrylonitrile, and 120 parts by weight of deionized water are mixed. To the mixture, 0.2 parts by weight of azobisisobutylonitrile (AIBN), 0.4 parts by weight of tricalcium phosphate and 0.2 parts by weight 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. Styrene-acrylonitrile copolymer (SAN) in a powder form is then obtained. The styrene-acrylonitrile copolymer (SAN) has a weight average molecular weight (Mw) of about 80,000 to about 100,000.
