Abstract
Pyrroles or mixtures of pyrroles with comonomers are polymerized electrochemically by anodic oxidation of the monomers in solution or dispersion in an electrolyte solvent, in the presence of a conductive salt, with deposition of the pyrrole polymer at the sheet-like anode, by a process in which the anode used consists of an electrically non-conductive sheet-like element which can be impregnated with the electrolyte solution and one or more electrically conducting support and contact strips which connects electrically to a current supply for the anode. The special anode for the electrochemical polymerization of pyrroles, and the products obtainable by the process.
