摘 要:以乙烯/马来酸酐共聚物为骨架,聚乙二醇单甲醚(M=550)为侧链,通过两步酯化,合成了梳状乙烯/马来酸酐共聚物多缩乙二醇酯,用IR、元素分析、交流复阻抗谱等对产物及其LiClO4盐复合物进行了研究。结果表明:所合成的产物为非晶的梳状聚合物,并严格按反应方程式生成半酯。盐浓度与电导率的关系在所研究的浓度范围内存在两个峰,一峰在O/Li+=8;另一峰在O/Li+=30。用侧链PEO玻璃化转变温度作T0,以logσ对1/T-T0作图,电导率与温度关系呈典型的VTF行为,该体系室温电导率最高可达2.58×10-5S/cm。おhe SPEs of new comblike polymers with ethylenemaleic anhydride copolymer as backbone,oligooxyethylene as side chains were synthesized by two step esterification method.The last productions and its LiClO4 complexes were charactrized by IR、elementary analysis and impedance technique.The results show that the synthesized products are noncrystallization,the essential reaction was complete and the product from this reaction was exactly a semiester.The relation between conductivity and salt concentration in the studied range has two peaks,one is O/Li+=8 and the other O/Li+=30.With glass transition temperature of side chain as T0,relation between conductivity and temperature abides VTF behavior.The conductivity at room temperature is 2.58×10-5S/cm.
