木素纤维素与丙烯腈接枝共聚物经碱溶液水解,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。随接枝量的提高,吸水率增加,到一定程度后趋于稳定。在碱性条件下,接枝共聚物中的氰基很快水解成羧酸盐和酰胺基,使接枝物具有一定的吸水性,随水解条件不同,水解产物结构不同,吸水率也不一样,在适当水解条件下可得到能吸收自重60～70倍水的木素纤维素聚合物。 The lignocellulose and acrylonitrile graft copolymer are hydrolyzed by alkali solution to obtain the lignocellulose absorbent material with certain water absorption property. The study found that the water absorption capacity of the material and the amount of grafting and hydrolysis conditions. With the grafting amount increased, water absorption increased to a certain extent stabilized. In alkaline conditions, the cyano group in the graft copolymer hydrolyzes quickly to carboxylate and amido groups, giving the graft a certain degree of water absorption. Depending on the hydrolysis conditions, the hydrolysis products have different structures and different water absorption rates , In the appropriate hydrolysis conditions can be obtained by absorbing 60 to 70 times the weight of water lignocellulosic polymer.
