摘　　要：:通过测定混合体系粘度、紫外、红外及DSC谱图 ,研究了聚乙烯吡咯烷酮(PVP)与水解聚丙烯酰胺 (HPAM )之间的相互作用 .结果表明 ,PVP/HPAM混合体系的增比粘度比单一体系增比粘度的简单加和大得多 ,并且PVP的加入增大了HPAM的抗盐性 .光谱结果显示 ,在溶液中二者通过静电力可形成超分子复合物 .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.
