摘要
摘要 Ishigaki 等人实验研究了丙烯酸在聚乙烯膜上进行接枝共聚反应。但用传统的动力学方法具体描述在不同的外界因素影响下的反应过程是相当困难的。本文对前人的实验数据,进一步研究了外界因素的影响规律,按作者提出的拟合曲线逼近法给出如下方程:D=[a+bexp(-t~θ)]^(-1),可定量地表达接枝率 D 与时间 t 之间的变化关系,有利于对聚合反应进行描述,方法简捷具有普适性(许多接枝共聚反应都符合这一规律性)。
Ishigaki et al.have investigated some factors influencing the radaition graftpolymerization of acrylic acid such as temperature,irradiation dose and monomer concen-tration.On the basis of their experimental data,the regularity of the factors mentionedabove were further discussed here.A general kinetic formula D=[a+bexp(-t^0)]^(-1)was de-rived by regression simulation,which can describe quantitatively the effects of all these fac-tors and is simpler in form.
