用交流复阻抗谱和动态粘弹谱等对交替马来酸酐共聚物多缩乙二醇酯衍生物及其ＬｉＣｌＯ４盐复合物进行了研究．结果表明，在Ｌｉ／ＥＯ＝０．０７—０．０４２范围内，从１７３Ｋ到３７３Ｋ，本聚合物一高氯酸锂复合体系的动态粘弹谱存在着两个明显的转变，其中β转变归属于ＰＥＯ的侧链玻璃化转变，转变温度随ＬｉＣｌＯ４盐浓度的增加而增加。α转变归属于主链玻璃化转变，在Ｌｉ／ＥＯ＝０．０２８时有极大值。盐浓度与电导率的关系与通常不一样，在所研究盐浓度范围内观察到两个峰，其一在Ｌｉ／ＥＯ＜０．０１４，另一峰在Ｌｉ／ＥＯ＝０．０２８．电导率与温度的依赖关系不符合Ａｒｒｈｅｎｉｕｓ行为；以ｌｇσ对１／Ｔ－Ｔ０作图，用侧链玻璃化转变温度Ｔβ作Ｔ０时，呈典型的ＶＴＦ行为。该体系室温电导率最高可达６×１０－６ｓ／ｃｍ．
Alternating maleic anhydride copolymer polyethylene glycol ester derivatives and their LiClO4 salt complexes were studied by means of AC complex impedance spectroscopy and dynamic viscoelastic spectroscopy. The results show that in the range of Li / EO = 0.07-0.042, there are two obvious changes in the dynamic viscoelastic spectra of the polymer-lithium perchlorate composite system from 173K to 373K, In the PEO side chain glass transition, the transition temperature increases with the increase of LiClO4 salt concentration. The α transition is attributable to the main glass transition, with a maximum at Li / EO = 0.028. The relationship between salt concentration and conductivity is generally not the same, with two peaks observed at the salt concentration studied, one at Li / EO <0.014 and the other at Li / EO = 0.028. The dependence of conductivity on temperature does not agree with the Arrhenius behavior; the typical VTF behavior is plotted for 1 / T-T0 with lgσ and T0 with the glass transition temperature Tβ of the side chain. The system room temperature conductivity up to 6 × 10-6s / cm.
