摘　　要：采用６０Ｃｏ－γ射线预辐照接枝法，研究了聚丙烯（ＰＰ）纤维与丙烯酸（ＡＡｃ）在苯中的接枝共聚反应。讨论了预辐照剂量、单体浓度、反应时间以及反应温度对接枝共聚反应的影响。实验结果表明，接枝率随预辐照剂量和反应温度的增加而增加。实验获得的接枝共聚物，其亲水性有明显的改善，但当预辐照剂量超过２Ｍｒａｄ时，机械强度有所下降。The effects of preirradiation dose, monomer concentration, reaction time and reaction temperature on grafting have been discussed. The results of experiment show that the grafting increases with the increase of preirradiation dose and monomer concentraiton. The products obtained from this experiment show that hydrophilicity is improved. But mechanical strength of products decreases with preirradiation dose over 2 Mrad compared with origonal sample.
