HETEROGENEOUS ANIONIC POLYMERIZATION PROCESS

摘要

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 particular to the homopolymerization of butadlene or isoprene, and to the copolymerization of isoprene-styrene.
