摘要

研究了在氮气气氛下丙烯酰胺在预辐照聚丙烯纤维上的接枝反应，以及预辐照剂量、接枝单体的浓度、接枝反应温度和时间对接枝率的影响。实验结果表明，接枝丙烯酰胺的最佳反应条件是：在乙醇和水（体积比为1:9）的溶剂化系统里，反应温度为70℃，反应时间为3h。并用ESR对引发接枝的机理进行了表征。

Abstract

In this paper, grafting reaction of acrylamide onto pre—irradiated polypropylene fibers in inert medium (N,2,) has been studied. The grafting degree has been determined as a function of radiation dose,monomer concentration, temperature and reaction time. The experimental results showed that the best condition of grafting reaction was 10% methanol/water solvent, temperature 70℃, and reaction time 3 h. The mechanism of grafting reaction was characterized with ESR.
