【Abstract】 The viscosity of the polyvinylpyrrolidone(PVP)/hydrolyzed polyacrylamide(HPAM)mixed systems have been studied.The experiment results indicated that the viscosity of mixed systems had synergic effect.Furthermore,the viscosity resistant to salt was enhanced by addition of PVP.The studies of the UV and FTIR spectra showed that PVP/HPAM supramolecular complexes were formed through not the hydrogen bond,but the electrostatic force.The Investigation of DSC showed that the polymer chains preferred to spread due to the formation of the complexes.更多还原
