Copolymerization of diallylamine (DAA) and itaconic acid (IA) was synthesized using benzoyl peroxide as a free radical initiator, in dioxane as the solvent. The composition of the copolymer was determined by the nitrogen content using Edx. The solubility of the copolymer was also investigated. The water solubility of the synthesized copolymer depends on the comonomers' ratio. The structure of the copolymer was confirmed by C-NMR spectroscopy. To increase the water insolubility of the copolymers, and keep their hydrophilicity, the copolymer was allowed to react with chitosan to form a superabsorbent polymeric material (SP). The structure of the synthesized superabsorbent was confirmed using C-NMR spectroscopy. The thermal property of the (SP) was also investigated by TGA. The investigation of the chitosan-based superabsorbent, as water-retaining agents, was studied. The results revealed that the superabsorbent polymers exhibited a good swelling ability and salt tolerance.
以过氧化苯甲酰为自由基引发剂，在二氧六环作为溶剂的条件下，合成了二烯丙基胺（DAA）和衣康酸（IA）的共聚物。使用能谱仪通过氮含量测定共聚物的组成。还研究了共聚物的溶解性。合成共聚物的水溶性取决于共聚单体的比例。通过碳-核磁共振光谱确认了共聚物的结构。为了增加共聚物的水不溶性并保持其亲水性，使共聚物与壳聚糖反应以形成高吸水性聚合材料（SP）。使用碳-核磁共振光谱确认了合成的高吸水性材料的结构。还通过热重分析研究了（SP）的热性能。研究了基于壳聚糖的高吸水性材料作为保水剂的性能。结果表明，高吸水性聚合物表现出良好的溶胀能力和耐盐性。
