摘要
根据该AN/VAC/甲基丙烯磺酸钠三元共聚体系特征,提出了该体系竞聚率测定的系统研究方案.根据竞聚率计算的原理,融汇二元共聚和三元共聚的基础理论,建立通用竞聚率计算数学模型,开发竞聚率计算软件,为非常规三元共聚体系竞聚率测定提供了新途径.
Via large number of experiments to explore the copolymerization reaction of AN/VAC/SMAS, a general understanding of the reaction characteristics is obtained. , thereby a method to measure the reactivity ratio(RR) of this system is proposed. Based upon the fundamental theory of RR, the equation for a binary copolymerization where the 2nd monomer does not polymerize itself and the equation for tertiary copolymerization where the 3rd monomer does not polymerize are devised . A versatile model we set to compute the RR, coupled with simplex numerical method is shown to increase the accuracy of the calculated RR value.
