실험 절차

Part A above was repeated except that 535 ml of acetone were introduced into the kettle in place of 480 ml of toluene and the vinyl acetate/maleic anhydride polymerization was carried out at 53° C. instead of 63-65° C. Esterification of the VA/MA was achieved with 262 g of absolute ethanol by conducting the reaction at 70-75° C. for about 3 hours. The acetone was distilled off and the vinyl acetate/ethyl maleate (VA/EM) alternating copolymer was recovered as a solution of 44.18% copolymer solids in ethanol having a relative viscosity of 1.26, a specific viscosity of 0.26 and a K value of 31.
