| 摘 要： | 以蔗渣纤维为原料，丙烯酸为接枝单体，N，N-亚甲基双丙烯酰胺为交联剂，K2S2O8为引发剂，通过溶液聚合的方法合成了蔗渣纤维（sugarcanebagasse，SCB）与聚丙烯酸（polyacrylicacid，PAA）的接枝共聚高吸水树脂（scB—g—PAA）。研究了丙烯酸用量、引发剂用量、交联剂用量以及中和度对吸水树脂吸水倍率的影响，结果表明，该接枝共聚吸水树脂的最佳合成条件是以丙烯酸用量为标准，蔗渣纤维、K2S2O8、交联剂用量分别是10％、2％、0．1％，中和度为80％，共聚物吸水倍率最高为765．7g·g-1。

| Abstract: | Superabsorbent polymer of sugarcanr bagasse fiber has been obtained by graft copolymerization of acrylic acid(AA) monomer using potassium persulfate(PP) as initiator in an aqueous medium.Grafting parameters were evaluated at different content of monomer,initiator,cross linker and neutralization.And the result had shown that the optimum condition for graft copolymerization is 10%,2%,0.1%,80% for the content of AA,PP,cross linker and neutralization,respectively.On the basis of Fourier transform infrared spectroscopy for the graft copolymer,the reaction steps for graft copolymerization have been proposed.The maximum absorption capacity of the copolymer for distilled water is 765.7g·g-1. |
