| 摘 要： | 以硝酸铈铵为引发剂,使壳聚糖与丙烯酸进行接枝共聚,测得共聚物中单体的接枝率为64％,接枝频率为1133,支链聚丙烯酸的分子量为31.7万。接枝共聚物经碱中和后制得吸水达1250倍以上的高吸水性树脂,并对其吸水速率,保水性,在不同电解质溶液中的吸水率及水饱和树脂在盐水中的失水率进行了测定。

| Abstract: | The graft copolymer of acrylic acid onto chitosan was prepared by using (NH_4)_2Ce(NO_3)_6 as initiator. The graft frequency and molecular weight have been determinded. The graft copolymer was neutralized by 8％ NaOH to give high water-absorbing resin which can absorb 1250 times of water (g/g). The properties and influential factors of this high water-absorbing resin have been studied. |
