| 摘 要： | 以K2S2O8-NaHSO3氧化还原体系为引发剂,合成了羧甲基纤维素（CMC）-丙烯酰胺（AM）-壳聚糖（CTS）接枝共聚物.研究了单体浓度、引发剂用量、反应温度、反应时间以及壳聚糖用量对接枝共聚反应的影响.采用红外光谱（FI-IR）对接枝聚合物进行了结构表征.结果表明：当AM=1.00 mol.L-1,引发剂（K2S2O8/NaHSO3=1∶1）浓度为5 mmol.L-1,mCTS/mCMC=1/5,反应温度55℃,反应时间3 h时,AM的转化率和接枝效率可分别达到76%和91%.

| Abstract: | Using K2S2O8-NaHSO3 redox system as trigger,a new graft-copolymer was synthesized called carboxy methyl cellulose(CMC)-acrylamide(AM)-crylamide chitosan(CTS).The effect of various factors such as reaction time,reaction temperature and intiator amount were investigated.The graft copolymer was characterized and analyzed by FT-IR.The result showed that polymerization rate and graft efficiency of acrylamide could reach 76% and 91% respectively when the conditions were as followed: the mass ratio of chitosan to ... |
