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 ethylenemaleic anhydride copolymer as backbone,oligooxyethylene as side chains were synthesized by two step esterification method.The last productions and its LiClO4 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 semiester.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 T0,relation between conductivity and temperature abides VTF behavior.The conductivity at room temperature is 2.58×10-5S/cm.
