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.
具有通式(I)的双亚胺钛配合物,其中:R1和R2,相互相同或不同,表示氢原子;或选自线性或支链、可选择卤代、C1-C20烷基基团,优选C1-C15,可选择取代的环烷基基团;R3和R4,相互相同或不同,表示氢原子;或选自线性或支链、可选择卤代、C1-C20烷基基团,优选C1-C15,可选择取代的环烷基基团,可选择取代的芳基基团;X1、X2、X3和X4,相互相同或不同,表示氯、溴、碘等卤素原子;或选自线性或支链C1-C20烷基基团,优选C1-C15,-OCOR5基团或-OR5基团,其中R5选自线性或支链C1-C20烷基基团,优选C1-C15;或表示乙酰丙酮基团(acac);但当R1和R2表示甲基基团且X1、X2、X3和X4表示氯原子时,R3和R4与2,6-二异丙基苯不同。
