摘要:介绍了半纤维素的化学组成和结构特点以及近20年来半纤维素醚化改性和用作造纸助剂的研究进展。主要阐述了使用不同醚化剂对半纤维素醚化改性，制备羧甲基半纤维素（阴离子半纤维素）、季铵化半纤维素（阳离子半纤维素）和两性离子化半纤维素及醚化改性后产品的应用研究现状，展望了半纤维素醚化改性的发展前景。

Abstract:The chemical composition and the structure characteristics of hemicellulose were briefly introduced, and the research progress of etherification modification of hemicelluloses and its application as papermaking additives in recent two decade were reviewed. The synthesis of carboxymethyl modified hemicellulose（anionic hemicelluloses）, quaternary ammonium hemicellulose (cationic hemicellulose) and amphoteric hemicellulose and the applications of these products were described in detail. Finally, the prospect of hemicellulose etherification modification was discussed.
