Process for the production of polyacetylene, wherein acetylene is polymerized in an organic diluent with the aid of an organometallic mixed catalyst based on a vanadium compound of the formula ##STR1## wherein R 1 represents halogen (chlorine), n R 2 and R 3 represent halogen (chlorine), OR 5 (R 5 =C 1 -C 20 alkyl, straight chain, cyclic or branched), whereby n R 2 and R 3 may be the same or different, n and on an luminium alkyl compound. |
