DISPERSIBLE POLYMER POWDERS

摘要

A water-dispersible powder (I) comprises polymer particles (T) with repeating thiophene units and at least one other polyanionic polymer (P). An independent claim is included for the production of the powder (P) by reaction of a dispersion or solution containing the polymer (T) and the polymer (P) with an organic precipitating agent in which the polymer (T) is insoluble, followed by separation and drying of the polymer.
