| 摘 要： | 采用黏度法研究了聚丙烯酰胺(PAM)与聚乙二醇(PEG)在水中的相互作用,发现当聚合物浓度较高时,PAM与PEG存在疏水作用、氢键以及相互缠结.两者间的相互作用随着聚合物浓度、PEG分子量以及PAM分子量的升高而增大;随着温度的升高,其相互作用先减小后增大;盐、乙醇以及丙烯酰胺的加入使相互作用减弱.

| Abstract: | 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... |
