    The determination and calculation of monomer reactivity ratio of the anionic copolymerization systems

    • 摘要: 用Tidwell-Mortimer非线性最小二乘法计算原理,在计算步骤上作了有意义的改进后,导出能用于高转化率下计算一般二元共聚体系竞聚率的公式。用它求得了在环己烷中以正丁基锂引发、添加二甘醇二甲醚(DG)(DG/n—BuLi=0.5)的丁苯共聚体系(50℃下)的表观竞聚率:~rB=2.119,~rS=0.074。将计算结果回代检验,与实验值吻合良好,并用TRS-80计算机求出了95%的椭圆形置信区域。
