series of highly acid-functionalized poly(phenylene oxide)s and poly(phenylene sulfone) were prepared and proton conductivity in their membranes is discussed. Phosphorylated poly(phenylene oxide)s were prepared via the oxidative polymerization of phosphonoxyphenols in alkaline water, along with a facile monomer preparation. A poly(phenylene oxide) bearing a sulfamide acid group was prepared by reacting amidosulfate
制备了一系列高度酸官能化的聚苯醚和聚苯砜,并讨论了它们膜中的质子传导性。磷酸化聚苯醚是通过膦氧苯酚在碱性水中的氧化聚合以及简单的单体制备来制备的。带有磺酰胺酸基团的聚苯醚是通过酰胺硫酸盐与相应的羧化聚苯醚反应制备的。通过磺化聚苯硫醚的过氧化氢氧化制备磺化聚苯砜。所有这些酸官能化聚合物都表现出基于芳族骨架的适当热稳定性。该聚合物具有高离子交换能力,可溶于水,但在与聚(环氧乙烷)复合后得到透明且柔韧的膜。一些膜在干燥条件下在 120°C 下显示出 10-4 S cm -1 的高质子传导率。
