Abstract
PURPOSE: To make the safe production possible, by adding an α-substituted aromaic vinyl compound in the production of a copolymer of an aromatic vinyl compound, maleic anhydride and a vinyl cyanide compound.
CONSTITUTION: The titled copolymer is obtained by continuously adding, to a monomer mixture consisting of (A) 0W5wt% maleic anhydride, (B) 0W20wt% α-substituted aromatic vinyl compound and (C) 100W75wt% aromatic vinyl compound which does not contain a substituent in the α-positon, a monomer mixture consisting of 20W35wt% compound A, 1W20wt% compound B and 79W45wt% compound C while polymerizing the monomers, further adding 10W20wt%, based on the total monomers, of a monomer mixture consisting of (D) 100W60wt% vinyl cyanide compound and 0W40wt% monomer copolymerizable with compound D after the conversion has reached 35W65wt%, based on the total monomer mixture charged, uniformly mixing the entire mixture and supension-polymerizing the mixture. Addition of compound C makes it possible to control the rate of copolymerization and to obtain safely a copolymer excellent in processability, mechanical strength and solvent resistance.
