The invention relates to a process for the preparation of electrically conductive polymers by polymerizing acenaphthylene, N-vinyl heterocycles such as N-vinylcarbazole or N-vinylpyridine or of N, N-divinylaniline at temperatures from -80 to + 100 ° C in the presence of a cationic catalyst , where as a catalyst an oxidizing Lewis acid, preferably FeCl 3 , FeBr 3 , SbCl 5 , SbF 5 , AsF s , CF 3 -S0 3 H or a combination of AlCl 3 or TiCl 4 with the compounds mentioned or with Cr0 3 or OsO 4 is used in amounts of 1 to 50 percent by weight. In the process, gaseous SbCl 5 , SbF 5 or AsF s can be applied to thin films of the monomers to be polymerized, applied to glass or polymeric supports, preferably plastic film. let absorb.n n n The electrically conductive polymers produced can be used in electrical engineering for the production of solar cells, for the conversion and fixation of radiation, for the production of electrical and magnetic switches or for the antistatic finishing of plastics. |
