摘要：以丙烯酸β羟乙酯（ＨＥＡ）－丙烯酸正丁酯（ＢＡ）共聚体系为研究对象，在共聚单体组成敏感点附近做重复实验，进行了６０°Ｃ，８０°Ｃ，１００°Ｃ，１２０°Ｃ，１４０°Ｃ下的共聚合，用１Ｈ－ＮＭＲ方法测定共聚物的组成，用Ｍａｙｏ－Ｌｅｗｉｓ微分组成方程的误差变量法计算竞聚率，同时给出竞聚率的９５％置信区间。
For the system of hydroethyl acrylate/butyl acrylate,solution copolymerization were carried out at two sensitive feed monomer composition points by duplicate experiments at 60°C,80°C,100°C,120°C,140°C respectively.The compositions of copolymer were analysized by NMR.The relative reactivity ratio of HEA and BA were calculated by the error in variables method (EVM) of Mayo Lewis equation,and 95% joint confidence intervals of the reactivity ratios were also given.According to the r 1 r 2 ,Arrhenius relation and activity energy difference between the homo and cross propagations were calculated too.
