| 摘 要： | 研究了以硝酸铈铵为引发剂合成纤维素/AM/AA接枝高吸水树脂的接枝共聚机理,其机理为自由基接枝共聚机理,包括链引发、链增长、键终止和氧化过程。通过IR谱实验特征谱的出现表明丙烯酰胺和丙烯酸已接枝到纤维素上。采用溴化法对接枝效率进行了测定,结果表明以硝酸铈铵为引发剂,高吸水树脂的接枝效率为76%。

| Abstract: | Reaction mechanism of a super absorbent resin (SAR) of cellulose/AM/AA, with (NH4)2Ce(No3)6as Initiator, has been studied, which is free radical mechanism that contains the process of chain initiation, chain growth, chain ending and oxidation. Identifying SAR by infrared spectroscopy (IR), the advent of characteristic peak has indicated that AA and AM have grafted on the chain of cellulose. Graft effectiveness of the SAR is determined with the method of bromine (Br) and up to 76%. |
