摘要
采用重量法对转化率进行了测定,用来确定竞聚率测定过程中前期聚合反应所需要的时间.运用核磁共振技术测定了共聚物的组成,并用直线交叉法和截距斜率法计算出丙烯酸六氟丁酯/丙烯酸丁酯/甲基丙烯酸甲酯的竞聚率.通过对竞聚率特点的分析对实验操作过程提出了改进意见.
Ratio - translation was determined by weight in this article and ratio - reactivity of action - time was certained. The compostion of copolymer was charactered with ^1H - NMR and ratio - reactivity of fluorinated - monomers, butyl - acrylate （BA） and methyl - lacrylate （ MMA）, was determined by Mayo - lewis and Fineman - Ross . Passed the analysis to gather the characteristics to ratio - reactivity to put forward to improving an opinion to the experiment operation process.
