Abstract

A process for the production of a suspension of doped polyacetylene particles, in which process acetylene is initially polymerized in a suspending agent with the formation of a suspension of polyacetylene particles in "burr" form, the catalyst is deactivated or removed, the solvent is optionally exchanged, and p- or n-doping is then carried out by adding a dopant additive in substance or in solution to the suspension.
