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 3):
A catalytic system for the (co)polymerization of conjugated dienes comprising:\n (a) at least one nitrogen titanium complex having general formula (I) or (II); (b) at least one co-catalyst selected from organic compounds of an element M\u2032 different from carbon, said element M\u2032 being selected from elements belonging to groups 2, 12, 13, or 14, of the Periodic Table of the Elements, including: boron, aluminum, zinc, magnesium, gallium and tin.
