Abstract: PURPOSE:To obtain the subject thermostable, transparent and chemical-resistant copolymer by initiating water-based suspension polymerization of vinyl cyanide and part of an aromatic vinylic monomer and comonomer with a specific polymerization initiator, adding the remainder of the aromatic vinyl compound while increasing the temperature and then completing the polymerization. CONSTITUTION:(A) The total amount of a vinyl cyanide-based monomer, (B) part of an aromatic vinylic monomer and (C) the total amount of a copolymerizable monomer are initially charged to initiate water-based suspension polymerization in the presence of a polymerization initiator having =95% to complete the polymerization. Thereby, the objective copolymer composed of 40-80wt.% component (A), 60-20wt.% component (B) and 0-20wt.% component (C) is obtained.
