(JP10507225-W)      A soluble, electroconductive polypyrrole has the formula (I).    A- = (i).    Also claimed is a method for preparing the above polypyrrole comprising polymerising pyrrole monomer in an aq. soln. contg. dodecylbenzene sulphonate ions as a dopant in the presence of a persulphate oxidant.    USE -   The polypyrrole is used in electroconductive coating materials and paints, electrode materials for batteries, semiconductor parts, electrolytes for solid electrolytic capacitors, solar cells for producing electricity etc.    ADVANTAGE -   The polypyrrole has superior solubility and may be cast into films and soln.-sprayed into coatings that have a very smooth surface. The smoother surface makes the electromagnetic functions of the conductive polymer more uniform and allows micro-devices to be formed with high reproducibility. Blends of the polypyrrole with other polymers that improve adhesiveness or strength allow smooth films to be formed on glass or polymers. Transparent electrode plates equivalent to glass plates with a transparent ITO coating may be formed.    (US5795953-A)      A soluble, electroconductive polypyrrole has the formula (I).
