Abstract:
Nitrogen titanium complex having general formula (I) or (II), wherein: —R 1  represents a hydrogen atom; or is selected from linear or branched C 1 -C 20  alkyl groups, preferably C 1 -C 15 , optionally halogenated, cycloalkyl groups optionally substituted, aryl groups optionally substituted; —R 2 , R 3 , R 4  and R 5 , identical or different, represent a hydrogen atom; or are selected from linear or branched C 1 -C 20  alkyl groups, preferably C 1 -C 15 , optionally halogenated, cycloalkyl groups optionally substituted, aryl groups optionally substituted, nitro groups, hydroxyl groups, amino groups; —Y represents a NH—R 6  group wherein R 6  represents a hydrogen atom, or is selected from linear or branched C 1 -C 20  alkyl groups, preferably C 1 -C 15 , optionally halogenated, cycloalkyl groups optionally substituted, aryl groups optionally substituted; or a N—R 7  group wherein R 7  is selected from linear or branched C 1 -C 20  alkyl groups, preferably C 1 -C 15 , optionally halogenated, cycloalkyl groups optionally substituted, aryl groups optionally substituted; —X 1 , X 2 , X 3  and X 4 , identical or different, represent a halogen atom, such as, for example, chlorine, bromine, iodine, preferably chlorine; or are selected from linear or branched C 1 -C 20  alkyl groups, preferably C 1 -C 15 , —OCOR 8  or —OR 8  groups wherein R 8  is selected from linear or branched C 1 -C 20  alkyl groups, preferably C 1 -C 15 ; or one of X 1 , X 2  and X 3  is selected from ethers, such as, for example, diethylether, tetrahydrofuran (THF), dimethoxyethane, preferably tetrahydrofuran (THF); —n is 1 in the case wherein Y represents a NH—R 6  group wherein R 6  has the same meanings reported above; or is 0 in the case wherein Y represents a N—R 7  group wherein R 7  has the same meanings reported above, or in the case wherein one of X 1 , X 2  and X 3  is selected from ethers; —R′ 1 , R′ 2 , R′ 3 , R′ 4 , R′ 5 , R′ 6  and R′ 7 , identical or different, represent a hydrogen atom; or are selected from linear or branched C 1 -C 20  alkyl groups, preferably C 1 -C 15 , optionally halogenated, cycloalkyl groups optionally substituted, aryl groups optionally substituted; —X′ 1  and X′ 2 , identical or different, represent a halogen atom such as, for example, chlorine, bromine, iodine, preferably chlorine; or are selected from linear or branched C 1 -C 20  alkyl groups, preferably C 1 -C 15 , —OCOR′ 8  groups or —OR′ 8  groups wherein R′  8  is selected from linear or branched C 1 -C 20  alkyl groups, preferably C 1 -C 15 ; —Y′ is selected from ethers such as, for example, diethylether, tetrahydrofuran (THF), dimethoxyethane, preferably is tetrahydrofuran (THF); or Y′ represents a group having general formula (III), wherein R′ 1 , R′ 2 , R′ 3 , R′ 4 , R′ 5 , R′ 6  and R′ 7 , have the same meanings as reported above; —m is 0 or 1. Said nitrogen titanium complex having general formula (I) or (II) can be advantageously used in a catalytic system for the (co)polymerization of conjugated dienes.

Claim (Index 12):
A process for the (co)polymerization of 1,3-butadiene or of isoprene (2-methyl-1,3-butadiene), wherein the catalytic system is used according to  claim 4 .
