Abstract

PURPOSE: To obtain an aromatic vinyl polymer having improved resistance to heat and solvents, and moldability, by copolymerizing an aromatic vinyl compound with maleic anhydride, and then a vinyl cyanide compound.
CONSTITUTION: (A) 60W90pts.wt. of an aromatic vinyl compound monomer and (B) 40W10pts.wt. of maleic anhydride and copolymerized in 10W70pts.wt. per 100pts.wt. of an organic solvent, e.g. acetone, which dissolves (A) and (B) in the first step. An aqueous solution of a suspension stabilizer, e.g. polyvinyl alcohol, is added to the polymerization system, and 20W45wt% of a vinyl cyanide monomer, and if necessary an aromatic vinyl compound are copolymerized in the second step. The resulting granular polymer is recovered in the third step.
