INTRINSISCH LEITFAEHIGES POLYMER IN FORM EINES DISPERGIERBAREN FESTSTOFFES, DESSEN HERSTELLUNG UND DESSEN VERWENDUNG

摘要

An intrinsically conductive polymer is in the form of a dispersible solid of primary particles with a specific surface area according to BET of > 15m<2>/g and with an average diameter of less than 500 nm, in which preferably not more than 20 % of aggregates with an average size > 1 mu m are present in the particle size range > 500 nm. For the manufacture of the polymer the polymerisation is carried out in a solvent in which the appropriate monomer is soluble or colloidally dispersible, but in which the polymer that is formed is insoluble, whereby the temperature of the reaction mixture is not allowed to rise more than 5 DEG C above the starting temperature.
