摘要
采用微波法合成羧甲基纤维素钠(CMC)-丙烯酰胺(AM)接枝共聚物。研究了接枝时间,引发剂用量,CMC/AM,初始温度等因素对接枝率的影响。结果表明,当接枝反应时间为3min,引发剂浓度为0.5mg/mL,CMC/AM为1/5,初始反应温度为30℃时,接枝率达62.69%。接枝共聚物对卵清蛋白溶液具有一定的缓释作用。
Synthesis of carboxymehtylcellulose （CMC） grafted onto acrylamide （AM）. with microwave radiation method has been carried in this experiment. The effects of the react time, the concentration of initiator, the proparation of CMC/AM, the initial temperature on the graft ratio were discussed, the results showed that while the reaction time is 3 minutes, [initiator]= 5 mg/mL, CMC/AM=1/5, the initial temperature is 30 ℃, the percentage of grafting reached 62.69%, The property of controlled release of CMC-g-AM copolymer was also studied.
