摘要
本文介绍两种用微机测算苯乙烯/α-亚甲基-δ-戌内酯共聚体系竞聚率的方法。一是笔者提出的微机动态搜索法,另一是非线性最小二乘法。给出了这两种方法的程序流程图,并按置信水平为95％时,计算了竞聚率r_1与r_2的联合置信区域。结果表明,笔者提出的方法具有良好的精确度。
The radical copolymerization of styrene (St) with α-methylene-δ-vaterolactone(MVL) of low ceiling temperature had been investigated by authors. The experimental results indicated that the Mago-lewis equation was quite adequate in describing the course of this copolymerization. In this paper, two methods of determination of reactivity ratios for St/MVL copo-lymer by microcomputer are introduced. One is microcomputer dynamic search method presented by authors, another one is none-linear least squares method. The program flow charts were given and the joint 95% confidence limits of reactivity ratios r1 and r2 were calculated. The results showed that the method presented by authors gave excellent accuracy.
