| 摘 要： | 研究了聚丙烯酸（ＰＡＡ）与聚乙二醇（ＰＥＧ）在浓溶液中的复合作用及影响因素，发现ＰＡＡ－ＰＥＧ在很宽的ＰＨ范围内都存在着复合作用。低ＰＨ时，通过氢键作用的形式进行复合，高ＰＨ时，则通过离子－偶极作用。对ＰＡＡ－ＰＥＧ－盐以及ＰＡＡ－盐复合膜进行了ＤＳＣ和Ｘ射线衍射分析，结果表明，ＰＡＡ与ＰＥＧ进行复合，可以破坏ＰＥＧ的结晶性能。

| Abstract: | The effects of PH,composition,concentration and temperature on solution viscosity were examined.It is found that the complex action between PAA and PEG occurs in wide range of pH.At low PH,it occurs by hydrogen bonding,while at high PH by ion-dipole interaction.The results of DSC and X-ray of the complex membrane show that the crystallinity of PEG could be destroyed by PAA. |
