希土類メタロセンを含む予備形成触媒系

Japanese Patent JP6959979

B2

A catalytic system based at least on isoprene as preformation monomer, on a metallocene of formula {P(Cp1)(Cp2)Y} and on an organometallic compound as cocatalyst, Y denoting a group comprising a metal atom which is a rare earth metal, Cp1 and Cp2, which are identical or different, being selected from the group consisting of fluorenyl groups, cyclopentadienyl groups and indenyl groups, the groups being substituted or unsubstituted, and P being a group bridging the two Cp1 and Cp2 groups and comprising a silicon or carbon atom, is provided. Such a catalytic system is soluble and exhibits an increased stability of the catalytic activity over time, in particular on storage.
