摘要/Abstract

摘要：利用氯离子选择电极，通过电极电位随氯离子浓度的变化，测定了VAC/DMC（醋酸乙烯/甲基丙烯酰氧乙基三甲基氯化铵）共聚物中PDMC链段的比例，从而计算出VAC和DMC的竞聚率分别为rVAC=0.48±0.12，rDMC=3.12±0.33，结果与元素分析法计算结果接近.

Abstract: By Cl--selective electrode,when the electropotential moves with the concentration of Cl-,proportion of PDMC in copolymerization of VAC/DMC(vinylacetic acid and methacyloyloxyethyl trimethylammonium chloride) can be determined.By this,Reactivity Ratios of VAC and DMC can be calculated as:rVAC=0.48±0.12，rDMC=3.12±0.33.This method is compared with element analysis,too.

Key words: reactivity ratios, electric potential analysis, VAC/DMC Copolymerization
