摘　　要：植物纤维原料的改性研究一直是一个很活跃的领域。研究了用铈铵体系引发杨木高得率浆与丙烯腈的接枝共聚反应,共聚物经二甲基甲酰胺抽提后再碱水解,可得到具有一定吸水性能的木素纤维素吸水材料。经研究发现该材料的吸水性能与接枝量和水解条件有关,在适当的反应条件下可得到能吸收自重40倍以上水的木素纤维素聚合物。The modification of plant fiber raw materials has been a very active area. Studied using cerium ammonium system caused HYP of poplar and graft copolymerization of acrylonitrile copotymer was extracted by DMF after alkaline hydrolysis can be obtained with a certain water absorption of lignin cellulose absorbent material. The study found that the absorbent material was associated with the conditions of grafting and hydrolysis, and in the appropriate reaction conditions can be obtained more than 40 times the weight of the water absorption of lignin cellulose polymers.
