  • Catalytic system for the stereospecific polymerization of dienes and use thereof in a process for synthesizing diene polymers
    Patent number: 12583949
    Abstract: A bimetallic catalytic system consists of the metallic components of formulae RLi and Ca(AR?y)2(L)x in which: R represents a substituted or unsubstituted C1-C10 aliphatic radical, a substituted or unsubstituted C6-C20 aromatic radical or a substituted or unsubstituted C1-C10 heteroaliphatic radical; A denotes N or C; y has the value 2 when A is N and the value 3 when A is C; each R? represents a hydrogen atom, a substituted or unsubstituted C5-C10 aliphatic radical, a substituted or unsubstituted C6-C20 aromatic radical, a substituted or unsubstituted silyl radical, a C1-C10 aliphatic radical substituted by at least one substituted or unsubstituted silyl radical, a C6-C20 aromatic radical substituted by at least one substituted or unsubstituted silyl radical; L represents a ligand; and x is a number ranging from 0 to 4.
