部分水解聚丙烯酰胺有机交联剂的研制

摘要

The polymer gel was synthesized from HPAM solution and polymer phenolic resin as the cross-linker.Then under different ratio of HPAM to polymer phenolic resin, change of the gel viscosity along with time was investigated,and the best ratio was gained. The results show that the higher the cross-linker concentration, the faster the crosslinking, the greater the gel viscosity, the best ratio of the polymer gel system is 2.5: 1, and the viscosity of the cross-linked gel is higher than uncross-linked HPAM gel.%以部分水解聚丙烯酰胺( HPAM)为主体,添加合成的酚醛树脂水溶液交联,形成的聚合物凝胶体系在不同质最浓度配比下粘度随时间的变化趋势,从而找到最佳的配比条件.结果表明,部分水解聚丙烯酰胺与酚醛树脂最佳的浓度比为2.5∶1,聚合物成胶后体系粘度在3h后达到最大值,胶液粘度稳定后与未交联的胶液相比粘度大为提高.
