Bis-imine titanium complex, catalytic system comprising said bis-imine titanium complex and process for the (co)polymertzation of conjugated dienes

Abstract

Bis-imine titanium complex having general formula (I): wherein: Rand R, mutually identical or different, represent a hydrogen atom; or are selected from linear or branched, optionally halogenated, C-Calkyl groups, preferably C-C, optionally substituted cycloalkyl groups; Rand R, mutually identical or different, represent a hydrogen atom; or are selected from linear or branched, optionally halogenated, C-Calkyl groups, preferably C-C, optionally substituted cycloalkyl groups, optionally substituted aryl groups; X, X, Xand X, mutually identical or different, represent a halogen atom such as chlorine, bromine, iodine; or are selected from linear or branched C-Calkyl groups, preferably C-C, —OCORgroups or —ORgroups wherein Ris selected from linear or branched C-Calkyl groups, preferably C-C; or represent an acetylacetonate group (acac); provided that when Rand Rrepresent a methyl group and X, X, Xand Xrepresent a chlorine atom, Rand Rare different from 2,6-di-isopropylphenyl.
