摘要
研究了羧甲基纤维素—丙烯酰胺接枝共聚反应,对初始pH值、引发剂用量、单体浓度、初始温度等因素对反应的影响进行了探讨,得到了最佳引发体系:H2SO4-KMnO4以及最佳反应条件:单体浓度30%、引发剂浓度500mg/L、初始温度30℃、初始pH值9。
Synthesis on the graft copolymerization of carboxymethylcellulose with acrylamide has been put forword in this paper. The effects of the initial pH and temperature, the concentration of initiator and monomer are discussed. The results showed that the optimal system of initiation should be: H2SO4-KMnO4 and the optimal condition should be: the monomer concentration is 30%, the initiator concentration is 500 mg/L, the initial temperature is 30℃, the initial pH is 9.
