The 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.
