磺化聚苯醚离聚体的合成及溶液性质研究

SYNTHESIS OF S-PPO AND THE AGGREGATION BEHAVIOR OF SALTS

合成一系列磺化度的磺化PPO(S-PPO),以磺化度为20.9mol％的S-PPO的钠盐和锂盐为代表,研究其在四氢呋喃/甲醇混合溶剂中的离聚体行为。结果表明,S-PPO离聚体在溶液中的链聚集状态与聚合物浓度、反离子半径和温度密切相关。

A series of sulfonated poly(2,6 dimethy1-1,4-phenytene oxide)(S-PPO)were synthesized.IR,NMR and titration were used to characterize the structures of the polymers.The solution behavior of S PPO with 20.9mo.1％ of sulfonated group and its ionomers in a mixting solvent of THF/MeOH(11/7 by volume) were studied.It was shown that the polymers displayed the typical ionomer properties.
