Abstract
Process for preparing specific oxidants which in mixtures with precursors for preparing conductive polymers display a long processing time during the polymerization; oxidants obtainable by this process; mixtures comprising such specific (retarding) oxidants and the use of said oxidants for preparing solid electrolyte capacitors and conductive layers.
Claims13
A process for the oxidative polymerization of precursors for the preparation of conductive polymers, the process comprising:
- providing a metal salt of an organic acid or an inorganic acid having organic radicals;
- preparing an oxidant by contacting the metal salt with an ion exchanger;
- mixing the oxidant with at least one conductive polymer precursor for preparing at least one conductive polymer;
- and
- separating the ion exchanger from the oxidant before mixing the oxidant with the at least one conductive polymer precursor.
