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。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.
