本文研究了以Fe~(2+)—H_2O_2为引发剂引发甘蔗髓与丙烯腈的接枝共聚反应。研究了亚铁含量,H_2O_2浓度,单体量,反应液比、温度和时间对接枝反应的影响;探讨了接枝共聚物碱水解条件,如碱浓度和用量、水解温度和时间、接枝增量等因素对水解产物吸水性能的影响。结果表明,在一定的条件下可获得较高接枝增量的接枝共聚物,降低反应液比或增加单体量均可明显提高接枝增量,接枝增量对水解产物吸水性能的影响不大。
In this paper, the graft copolymerization of sugarcane pulp with acrylonitrile initiated by Fe ~ (2 +) - H_2O_2 was studied. The effects of ferrous content, H 2 O 2 concentration, monomer amount, reaction liquid ratio, temperature and time on graft reaction were investigated. The alkali hydrolysis conditions of the graft copolymer such as alkali concentration and amount, hydrolysis temperature and time, grafting Influence of factors such as increment on water absorption of hydrolyzate. The results showed that under certain conditions, graft copolymers with higher grafting degree could be obtained. Decreasing the reaction liquid ratio or increasing the amount of monomers could obviously increase the grafting increment, Has little effect.
