PROCESS FOR THE PREPARATION OF ELECTRICALLY CONDUCTIVE POLYMERS

摘要

1. Process for the production of electrically conductive polymers, characterised in that, in a first stage, an aromatic compound which contains 2 to 9 carbocyclic rings and optionally 1 to 3 heterocyclic rings containg O, S or N as the heteroatom and is optionally substituted with alkyl, carbonyl, carboxyl and/or sulphonyl groups, is reacted at 80 to 400 degrees C in a molar ratio of 1 to 0.5 to 100 with sulphur, a corresponding quantity of a sulphur-donating agent, selenium or mixtures thereof and in a second stage the high molecular weight reaction product is oxidised to produce p-conductivity or reduced to produce n-conductivity.
