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.
Claims6
A process for the electrochemical polymerization of a pyrrole or a mixture of a pyrrole with a comonomer 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 on a sheet-like element of the anode, said anode consisting essentially of a porous, electrically non-conductive, sheet-like element which can be impregnated with said electrolyte solution or dispersion and one or more electrically conducting support and contact strips integral with and in functional relationship with said sheet-like element by electrically connecting said sheet-like element with the anode current supply.
