摘要
对聚丙烯（ＰＰ）纤维辐射接枝４＿乙烯基吡啶（４ＶＰ）的反应动力学进行了研究．建立了接枝反应速率方程：Ｒｇ＝ｋ［Ｍ］１．１７Ｄ０．５６．求得接枝反应的表观活化能和表观碰撞频率因子分别为７．９５ｋＪ／ｍｏｌ和６５．６，并建立了如下公式：ｌｎＲｇ＝１．１７ｌｎ［Ｍ］＋０．５６ｌｎＤ－７９２．６４／Ｔ＋４．
In this paper, the kinetics of radiation_induced grafting reaction of 4_vinyl pyridine (4VP) onto polypropylene (PP) fiber is investigated, and the velocity equation of the reaction is established as following: R g =k 1.17 0.56 . The apparent activation energy and the apparent collision frequency factor of the grafting copolymerization are 7.95 kJ/mol and 65.6, respectively. Then the following equation is established: ln R g =1.17 ln +0.56 ln -792.64/T+ 4.18.
