摘　　要：考察了复合溶液的复合比、复合物浓度、Na Cl浓度、温度、剪切速率及 p H等因素对疏水化两性离子纤维素接枝共聚物 /疏水化聚丙烯酰胺复合溶液粘性行为的影响 .结果表明 ,与复合溶液的单组分相比 ,复合溶液具有很好的协同增粘性能 ,良好的耐盐、耐温和抗剪切增粘性能 ,以及在 pThe viscosity behavior of the aqueous complex solution of hydrophobically modified amphoteric cellulosic graft copolymer and hydrophobically modified polyacrylamide have been investigated as a function of complex ratio, complex concentration, NaCl concentration, temperature, shear rate and pH by means of Haake Rheometer. The results show that the complex solution exhibits better synergistic viscosity than the single constituent, excellent resistances to salt, temperature and shear rate, and has a maximum viscosity at pH=7.
