Reaction Conditions

Reaction Steps

Into a 2 L reactor equipped with an agitator, a thermometer, a nitrogen gas inlet tube, a dropping funnel, and a reflux condenser, was placed 600 g of distilled water, 0.71 g of sodium dodecyl sulfate as an emulsifier, and as monomers, 70 g of acrylonitrile and 30 g of n-butyl acrylate, and the reactor was nitrogen-purged while the reaction mixture was being stirred at 80° C. Next, 1.6 g of 4,4′-azobis(4-cyanovaleric acid) as a polymerization initiator together with 30 g of distilled water was added into the reactor, and a reaction was initiated. Stirring was performed at 80° C. for 10 hours, and an acrylonitrile/n-butyl acrylate random copolymer was produced with a conversion rate of monomers of 89%. GPC measurement confirmed that Mw=472,000, Mn=214,000, and Mw/Mn=2.21.
