    Description / Table of Contents: Monomere mit Pyrrol-Einheiten und dem Strukturelement der Schiffschen Basen wurden durch elektrochemische Oxidation bei gleichzeitiger Fällungspolymerisation in 1,2-Dichlorethan oder Acetonitril hergestellt. Als Monomere wurden Pyrrol-2-aldehydazin, N,N'-bis(2-pyrrolylmethylen)-1,4-diaminobenzol bzw. N,N'-bis(2-pyrrolylmethylen)-4,4′-diaminobiphenyl und als Elektrolyte Tetrabutylammoniumperchlorat, Tetrabutylammoniumtetrafluoroborat sowie Natrium-p-toluolsulfonat eingesetzt. Die dotierten Polymeren wurden mittels Elementaranalyse, IR-Spektroskopie und Thermoanalyse charakterisiert.
    Notes: Pyrrole-2-aldehyd azine, N,N'-bis(2-pyrrolylmethylene)-1,4-diaminobenzene and N,N'-bis(2-pyrrolylmethylene)-4,4′-diaminobiphenyl were polymerized by electro-chemical precipitating oxidation reaction in 1,2-dichloroethane and acetonitrile, respectively, in the presence of electrolytes like tetrabutylammonium perchlorate, tetrabutylammonium tetrafluoroborate and sodium p-toluene sulfonate. The doped resulted polymers were characterized by elemental analysis, IR spectroscopy and thermal analysis.
