  • Heterogeneous anionic polymerization process
    Patent number: 4130703
    Abstract: The present invention relates to a heterogeneous anionic polymerization process, catalysed 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 butadiene or isoprene, and to the copolymerization of isoprene-styrene.
    Type: Grant
    Filed: March 2, 1978
    Date of Patent: December 19, 1978
    Assignee: Agence Nationale de Valorisation de la Recherche (ANVAR)
    Inventors: Ilia Rashkov, Jean Gole, Daniel Guerard, Albert Herold, Gerard Merle, Ivan M. Panayotov, Jean-Pierre Pascault, Quang T. Pham, Christian Pillot, Robert Salle
