Firstly,the reactivity ratios of radical copolymerization are determined by intercept-slope method, YBR method, JJ method (linear intersect), TM method (non-linear least squares) and microcomputer dynamic search method using microcomputer.

• 第一方面：利用计算机，通过截距斜率法、YBR法、JJ法(直线交叉法)、TM法(非线性最小二乘法)和动态搜索法测算共聚体系竞聚率，其中TM法和动态搜索法获得比较精确的竞聚率结果。
