摘要
本文详细地研究了羊毛用^(60)Coγ射线引发甲基丙烯酸甲酯和丙烯腈混合接枝共聚反应动力学。建立了接枝共聚反应速度方程:R_g=k’[M]_0^(0.8)D^(0.35)[D为剂量率(kGy/h)]。接枝共聚反应的表观活化能和碰撞频率因子分别为14.23kJ/mol和278 g％h^(-0.65)kGy^(-0.35)mol^(-0.8)L^(0.8)。并建立了如下公式: lnR_g=5.63-1710(1/T)+0.8ln[M]_0+0.
In this paper, kinetics of the ^(60)Co gamma ray induced graft copoly-merization of mixture of methyl methacrylate and acrylonitrile onto wool was studiedin detail. The results shown the following functional relationship equation: R_g=k'[M]_0^(0.8)D^(0.35)The apparent activation energy and the collision frequency factor of the grafting copo-lymerization are 14. 23 kJ/mol and 278g%h^(-0.65)kGy^(0.35)mol^(-0.8)L^(0.8).,respectively. The work established that the relationship of the grafting copolymerization ratewith T, [M]_0, and D relational expression at arbitrary temperature: lnR_g=5. 63-1710 1/T +0.8 ln[M]_0+0.35 lnD.
