Abstract
Electrically conductive, finely divided pyrrole polymers are prepared by a process in which a pyrrole is polymerized in the presence of a carrier and are used for the production of shaped articles and coatings.
Claims7
A process for the preparation of an electrically conductive, finely divided pyrrole polymer which comprises polymerizing a pyrrole by anodic oxidation at a temperature of from - 30.degree. to +100.degree. C. in the presence of a finely divided carrier suspended in an auxiliary liquid, said carrier having a mean particle size of from 0.001 to 1000 .mu.m and a specific surface area of from 10 to 1000 m.sup.2 /g, and in the presence of a conductive salt, said conductive salt and said pyrrole being dissolved in the auxiliary liquid.
