含苯并氮杂15-冠-5侧基的线型聚硅氧烷促进液膜离子传输性能

N-十一碳烯和N-烯丙基苯并氮杂15-冠-5和甲基二氯硅烷硅氢加成后, 再与端羟基聚二甲基硅氧烷反应, 用三甲基氯硅烷封端, 合成了两种含苯并氮杂15-冠-5侧基的线型聚硅氧烷。分别以两种聚合物为液膜离子传输载体, 研究了载体种类、阴离子、阳离子种类及载体浓度和盐浓度对离子传输速率的影响, 并考察了膜的稳定性。

Linear polysiloxanes with pendant benzo-aza-15-crown-5 mediated ion transport

N-undecenyl and N-allyl benzo-aza-15-crown-5 were subjected to hydrosilylation with methyldichlorosilane, followed by polycondensation with silanol-terminated polydimethylsiloxane to give the crown functionalized linear polysiloxanes. Studies were reported of the variation of cation transport rate through a bulk liquid membrane containing crown functionalized linear polysiloxanes with the kind of polysiloxanes, cation and anion thpe, and with carrier concentration, salt concentration. The stability of the membrane was also investigated.
