VISCOMETRIC STUDIES ON THE INTERACTION BETWEEN POLYACRYLAMIDE AND POLY(ETHYLENE GLYCOL) IN WATER
黏度法研究聚丙烯酰胺与聚乙二醇在水中的相互作用

In order to clarify the interaction between the continuous phase and the dispersion phase rich in polyacrylamide(PAM),the interaction between PAM and PEG in water was studied by viscosity method.In a dilute aqueous solution of PAM,the segments of PAM molecular chains prefer to combine with water molecules through hydrogen bonding.However,the hydrogen bonding between PAM molecular chains increased with increasing concentration of PAM in water.Because the aqueous PEG solution is a poor solvent for PAM,the PAM...
