ABSTRACT:
The electrical conductivity of solid, impregnable materials, such as cellulose-based insulating materials, can be increased by supplying to the solid impregnable material a substance with the ability, during polymerization of a pyrrole compound comprising at least one of the substances pyrrole and N-methylpyrrole, to give a polymer with higher electrical conductivity than the solid impregnable material, as well as a pyrrole compound of the kind stated, whereafter the pyrrole compound is transformed into a polymer in the solid, impregnable material.
