In this work, gamma irradiation from a cobalt ⁶⁰Co source was used to graft Copolymerize α-methyl styrene (AMS) onto Polyethersulfone (PES) films. Grafting reaction was performed at ambient temperature by simultaneous method applying different dose rates for a total absorbed dose of 30 kGy. The effects of reaction conditions including, dose rate, monomer concentration and absorbed dose on the grafting yield (DOG) were studied. Results showed that the grafting conditions influence considerably DOG. In addition, the depth understanding of the graft copolymerization reaction kinetics under various reactions conditions have permitted establishing the dependence of the initial rate of grafting as a function as monomer concentration and dose rate and was expressed by the following equation: \(\frac{{dG_{0} }}{dt}\alpha \left[ M \right]^{2} \left[ D \right]^{0.47}\).

反应条件对γ辐射诱导的α-甲基苯乙烯接枝聚合在聚醚砜薄膜上的影响：动力学研究

^{在这项工作中，来自钴60} Co 源的伽马辐射用于将 α-甲基苯乙烯 (AMS) 接枝到聚醚砜 (PES) 薄膜上。接枝反应在环境温度下通过同时应用不同剂量率的方法进行，总吸收剂量为 30 kGy。研究了剂量率、单体浓度和吸收剂量等反应条件对接枝率（DOG）的影响。结果表明，嫁接条件对DOG的影响很大。此外，对各种反应条件下接枝共聚反应动力学的深入了解，允许建立初始接枝率作为单体浓度和剂量率的函数的依赖性，并由以下等式表示：\(\frac{{dG_{0} }}{dt}\alpha \left[ M \right]^{2} \left[ D \right]^{0.47}\)。
