摘要
研究了以硝酸铈铵作引发剂、N,N′-亚甲基双丙烯酰胺作交联剂制备聚乙烯醇-丙烯酰胺接枝共聚型吸水树脂的方法,运用正交设计法,找出了影响产品吸水量和吸湿量诸因素的排列次序和各自的最佳条件,红外光谱测试分析表明反应生成了接枝共聚物,所得产品吸蒸馏水能力为1200倍左右,95%RH下的吸湿量为1.6倍左右。
The method of preparation polyvinyl alcohol-aerylamide graft eopolymerization super absorbent polymer which used the initator of ammonium cerium nitrate and the cross-linking agent of N, NCmethylene diacrylamide was studied. The factors and the best condition which affected the product water absorption quantity and absorption humidity quantity was found with the method of orthogonal design. The graft copolyrnerization was created by the test result of infra-red absorption spectroscopy. The product can absorb the distillation water 1200 times and absorb the humidity quantity 1.6 times on the condition of relative humidity 95%.
