Abstract In this paper, maleic anhydride (MA) was grafted onto methyl cellulose (MC) and then reacted with acrylic acid to synthesize a high gel strength and fast water absorption resin (AA-co-MC-g-MA) by UV polymerization. The reaction conditions of maleylated methylcellulose (MC-g-MA) were investigated, including the ratio of MC to MA, reaction time and catalyst amount. In addition, the reaction conditions for the synthesis of super absorbent resin were as follows: the amount of MC-g-MA, the degree of substitution of MC-g-MA, polymerization time, and the amount of initiator. Under optimal conditions, the maximum water absorption volume of synthetic resin was 2116 g/g, and the maximum salt absorption rate was 139 g/g. The water absorption resin prepared this time had high water absorption, water retention, excellent pH sensitivity, etc. It was hoped that it will have a good application prospect in the field of industrial production and agriculture in the future.

马来酰化甲基纤维素丙烯酸吸水树脂的紫外聚合及性能分析

摘要 本文将马来酸酐（MA）接枝到甲基纤维素（MC）上，然后与丙烯酸反应，通过UV聚合合成了一种高凝胶强度和快速吸水的树脂（AA-co-MC-g-MA）。考察了马来酰化甲基纤维素（MC-g-MA）的反应条件，包括MC与MA的比例、反应时间和催化剂用量。此外，合成高吸水性树脂的反应条件为：MC-g-MA的用量、MC-g-MA的取代度、聚合时间和引发剂的用量。在优化条件下，合成树脂的最大吸水量为2116 g/g，最大吸盐率为139 g/g。本次制备的吸水树脂具有吸水率高、保水性好、pH敏感性优良等特点。
