In the present communication, the electropolymerisation of sodium 2-(3
-thienyl)ethyl sulfonate (TES) and the copolymerisation of sodium 2-(3
-thienyl)ethyl sulfonate monomer with pyrrole in an aqueous medium are
reported. It has been shown that TES can be oxidised/polymerised in a
n aqueous solution. The polypyrrole/polyTES copolymer can be obtained
from a mixed solvent system. The polymers obtained (either in solution
or on the electrode surface) were characterised using NMR, mass spect
roscopy and/or elemental analysis.
