  磺化共聚醚砜的合成与表征

  摘要：

  本文讨论了一些磺化共聚醚砜的合成和表征。合成方法不同于文献中传统报道的后磺化方法。合成程序是基于使用磺化单体，然后将其与先前合成的远螯加氢封端的聚（醚磺胺酮）反应。结合MALDI-TOF MS和11 H NMR分析以及SEC粘度法和TGA测量结果证明了一种用于表征二磺化聚亚芳基醚砜共聚物的化学组成，端链，磺化度（DS）和分子质量分布（MMD）的强大工具。表征技术可以确定合成共聚物的确切性质，并揭示有关反应的一些有趣特征。DMA数据表明，具有相似DS的磺化共聚物的玻璃化转变温度随其MMD的升高而升高。DS为10-11 mol％的共聚物的T g为244-246°C。©2010 Wiley Periodicals，Inc.

  Block copolymers containing blocks of unsulfonated aromatic polyether sulfones and blocks of aromatic polyether sulfones sulfonated on the aromatics are characterized in that the block length of the unsulfonated aromatic polyether sulfones in each case comprises at least 10 repeating units and that the sequence of the main chain at the block transitions between two adjacent blocks of aromatic polyether sulfones is the same as it is inside these blocks. These block copolymers may be prepared by polycondensation, and are preferably used as membranes. The block copolymers provide compounds which in addition to an adjustable degree of sulfonation have a defined length of sulfonated and unsulfonated blocks. As a result, the spectrum of the polymers suitable for the preparation of synthetic membranes can be expanded and graded.
