EVA—VC接枝共聚动力学的研究

进行了在氯乙烯饱和蒸气压以下 EVA-VC 接枝共聚动力学的研究。假设了一个反应历程,据此推导出动力学方程式,并作了实验验证。结果表明,聚合速度与单体浓度的1次方和引发剂用量的1/2次方成正比。此外,利用动力学方程式求得了各基元反应速度常数的比值。

(?)netics Study of Graft Polymerization of Viny(?) Chloride onto Ethylene-Vinyl Acetate Copolymer

The kinetics of graft polymerization of VC onto EVA has been studied under sub-saturation pressure of VC,and the kinetic equations have been derived accord- ing to a proposed mechanism.Experimental results show that the rate of poly- merization is proportional to the monomer concentration,and to the amount of initiator employed raised to the 0.5th power.Furthermore,the rate constants of elementary reactions have been evaluated by the kinetic equations.
