摘要
以水为反应介质,在过硫酸铵的引发下,合成了糊精(?)丙烯酰胺接枝共聚物,对单体浓度,引发剂浓度,反应温度和反应时间对接枝率的影响进行了研究。然后加入甲醛作为交联剂,研究了交联剂的浓度,pH 值,温度和时间对交联程度的影响。最后在上述已交联的接枝共聚物中加入各种改性剂,合成了新型再湿胶,经测试各种性能优异,有很好的应用价值。
Synthesized graft copolymer of dextrin and acrylamide by ammonium persulfate initiator.Investigated the influence of monomer concentration,initiator concentration, reaction temperature and time on grafting efficiency.Then added formaldehyde as cross linking agent,studied the effect of formaldehyde concentration,pH and tem- perature on crossing degree.At last,produced new type of adhesive by mixing var- ious modifiers,it has good properties and applied value.
