The decrease of conductivity in poly(pyrrole)M when a substituent is introduced into the polymer either at the nitrogen or in the β positions is investigated. The drop in conductivity is two orders of magnitude by sbstitution in the 3 (β) position and five orders of magnitude when the substitution is made a nitrogen, in the 1‐position. The various factors affecting te conductivity are analyzed for a series of oligomers with between one and six pyrrole units.
