Controlled potential reduction at an Hg pool cathode of 2,5-bis(bromomethyl)benzenesulfonic
acid, 2,5-bis(dibromomethyl)benzenesulfonic acid and the analogous
benzoic acids, in aqueous solution with ammonium acetate or lithium nitrate
electrolyte, is an efficient route to the corresponding water-soluble
PPX and PPV polymers. Co-electrolyses of combinations of these precursors
yield water-soluble random co-polymers. The polymers were primarily
examined by gel-permeation chromatography, FTIR, 1H and 13C
NMR (solution and solid state). The sulfonic acid substituted PPX
forms insoluble complexes or salts with Ba2+, Fe3+
and Cu2+.
在醋酸铵或硝酸锂电解质的水溶液中,2,5-双(溴甲基)苯磺酸、2,5-双(二溴甲基)苯磺酸和类似的苯甲酸在汞池阴极的受控电位还原是获得相应的水溶性 PPX 和 PPV 聚合物的有效途径。将这些前体组合进行共电解可得到水溶性无规共聚物。这些聚合物主要通过凝胶渗透色谱法、傅立叶变换红外光谱、1H 和 13C NMR(溶液和固体状态)进行检测。磺酸取代的 PPX 与 Ba2+、Fe3+ 和 Cu2+ 形成不溶性复合物或盐。
