ABSTRACT OF THE DISCLOSURE The present invention relates to a heterogeneous anionic polymerization process, catalyzed by a metallic insertion graphitic compound. According to the invention, the alkaline metal chosen for the insertion compound is lithium, and the insertion compounds are of binary or ternary type ; in the latter case, the insertion compound may comprise an aromatic hydrocarbon also inserted within the graphitic structure. The invention relates in particu- lar to the homopolymerization of butadlene or isoprene, and to the copolymerization of isoprene-styrene.
