本论文着重论述了纤维素在均相体系中的接枝共聚研究进展,分析了纤维素在Li Cl/DMAc、碱/尿素以及离子液体等溶剂体系下的溶解机理,进而重点介绍了纤维素在各溶剂体系中的均相接枝共聚反应机理和反应效果。分析发现,纤维素在离子液体中具有更高的接枝率,在Li Cl/DMAc体系中的接枝温度明显高于在其它溶剂体系中的接枝温度,在Li Cl/DMAc和离子液体体系中的接枝时间要低于其它溶剂体系。以上分析对于纤维素的功能化改性具有一定的借鉴意义和参考价值。
This dissertation focuses on the research progress of graft copolymerization of cellulose in the homogeneous system, and analyzes the dissolution mechanism of cellulose under the solvent system of LiCl / DMAc, alkali / urea and ionic liquid, Homogeneous Graft Copolymerization Mechanism and Reaction Effect in Each Solvent System. The results showed that cellulose had a higher grafting rate in ionic liquid, the grafting temperature in LiCl / DMAc system was significantly higher than that in other solvent systems, and in LiCl / DMAc and ionic liquid system In the grafting time is lower than other solvent systems. The above analysis for the functional modification of cellulose has some reference and reference value.
