Abstract:
(EN) Bis-imine titanium complex having general formula (I): wherein: R1 and R2, mutually identical or different, represent a hydrogen atom; or are selected from linear or branched, optionally halogenated, C1-C20 alkyl groups, preferably C1-C15, optionally substituted cycloalkyl groups; R3 and R4, mutually identical or different, represent a hydrogen atom; or are selected from linear or branched, optionally halogenated, C1-C20 alkyl groups, preferably C1-C15, optionally substituted cycloalkyl groups, optionally substituted aryl groups; X1, X2, X3 and X4, mutually identical or different, represent a halogen atom such as chlorine, bromine, iodine; or are selected from linear or branched C1-C20 alkyl groups, preferably C1-C15, -OCOR5 groups or -OR5 groups wherein R5 is selected from linear or branched C1-C20 alkyl groups, preferably C1-C15; or represent an acetylacetonate group (acac); provided that when R1and R2 represent a methyl group and X1, X2, X3 and X4 represent a chlorine atom, R3 and R4 are different from 2,6-di-/'so-propylphenyl.
(FR) La présente invention concerne un complexe de bis-imine titane ayant la formule générale (I) : où : R1 et R2, mutuellement identiques ou différents, représentent un atome d'hydrogène; ou sont sélectionnés parmi les groupes alkyle en C1 à C20 linéaires ou ramifiés, éventuellement halogénés, préférablement les groupes cycloalkyle en C1 à C15, éventuellement substitués; R3 et R4, mutuellement identiques ou différents, représentent un atome d'hydrogène; ou sont sélectionnés parmi les groupes alkyle en C1 à C20 linéaires ou ramifiés, éventuellement halogénés, préférablement les groupes cycloalkyle en C1 à C15, éventuellement substitués, les groupes aryle éventuellement substitués; X1, X2, X3 et X4, mutuellement identiques ou différents, représentent un atome d'halogène tel que le chlore, le brome, l'iode; ou sont sélectionnés parmi les groupes alkyle en C1 à C20 linéaires ou ramifiés, préférablement en C1 à C15, les groupes -OCOR5 ou les groupes -OR5 où R5 est sélectionné parmi les groupes alkyle en C1 à C20 linéaires ou ramifiés, préférablement en C1 à C15; ou représentent un groupe acétylacétonate (acac); à condition que lorsque R1 et R2 représentent un groupe méthyle et X1, X2, X3 et X4 représentent un atome de chlore, R3 et R4 sont différents du groupe 2,6-di-/'so-propylphényle.
