Preparation of electrically conductive polymers

Abstract

Abstract A process for the preparation of electrically conductive polymers by polymerizing acenaphthylene, N-vinyl-heterocyclics, eg. N-vinylcarbazole or N-vinylpyridine, or N,N-divinylaniline at from -80° to +100° C. in the presence of a cationtic catalyst, wherein from 1 to 50 percent by weight of an oxidizing Lewis acid, preferably FeCl 3 , FeBr 3 , SbCl 5 , SbF 5 , AsF 5 or CF 3 -SO 3 H, or a combination of AlCl 3 or TiCl 4 with the said compounds or with CrO 3 or OsO 4 is used as the catalyst. In a preferred embodiment of the process, thin films of the monomers to be polymerized, applied to glass or to a polymeric base, preferably to a plastic film, are treated with gaseous SbCl 5 , SbF 5 or AsF 5 . The conductive polymers obtained can be used in the electrical industry for the production of solar cells, for the conversion and fixing of radiation and for the production of electrical and magnetic switches, as well as for the antistatic treatment of plastics.
