摘要
采用聚丙烯(PP)无纺布为基材,甲基丙烯酸甲酯(MMA)为单体,^(60)Co-γ射线预辐射接枝共聚的方法制备接枝共聚物,讨论了辐射剂量、反应温度、反应时间、单体浓度、阻聚剂和交联剂的用量等对接枝率的影响。结果表明,接枝反应的最佳条件为:辐射剂量60 kGy以上、接枝温度65℃、接枝时间2 h、MMA质量分数20%、交联剂质量分数5%、阻聚剂用量0.3g,该条件下PP的接枝率为6.5%。
Methyl methacrylate (MMA) as a monomer was grafted on polypropylene (PP) non-woven fabric as a substrate by graft eopolymerization under ^60Co-T irradiation. The effects of irradiation dose, reaction temperature and time, monomer concen- tration, amounts of inhibitor and erosslinking agent on the graft yield were discussed. The results showed that the graft yield of PP could be 6.5% under the optimized conditions as follows: irradiation dose above 60 kGy, grafting temperature 65℃ and time 2 h, 20% MMA by mass fraction, 5% erosslinking agent by mass fraction and 0.3 g inhibitor.
