Controlled potential reduction at an Hg pool cathode of 2,5-bis(bromomethyl
)benzenesulfonic acid, 2,5-bis(dibromomethyl)benzenesulfonic acid and the a
nalogous benzoic acids, in aqueous solution with ammonium acetate or lithiu
m nitrate electrolyte, is an efficient route to the corresponding water-sol
uble PPX and PPV polymers. Co-electrolyses of combinations of these precurs
ors yield water-soluble random co-polymers. The polymers were primarily exa
mined by gel-permeation chromatography, FTIR, H-1 and C-13 NMR (solution an
d solid state). The sulfonic acid substituted PPX forms insoluble complexes
or salts with Ba2+, Fe3+ and Cu2+.
