Abstract:
Vanadium pyridine-imine complex having general formula (I), wherein:—R 1 , R 2 , R 3 , R 4 , R 5  and R 6 , equal to or different from each other, 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 , X 2  and X 3 , equal to or different from each other, 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 7  groups or —OR 7  groups wherein R 7  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 etrahydrofuran (THF);—n is 0 or 1. Said vanadium pyridine-imine complex having general formula (I) can be advantageously used in a catalytic system for the (co) polymerization of conjugated dienes.

Claim (Index 13):
The catalytic system of  claim 3 , wherein the co-catalyst comprises at least one selected from the group consisting of (b 1 ), (b 2 ), (b 3 ) and (b 4 ):\n (b 1 ) a compound having a formula (II):\n Al(R 9 )(R 10 )(R 11 )\u2003\u2003(II) \n wherein R 9  represents a hydrogen atom, a fluorine atom, or a linear or branched C 1 -C 20  alkyl group, cycloalkyl group, aryl group, alkylaryl group, arylalkyl group, or alkoxy group; R 10  and R 11  each independently represent a linear or branched C 1 -C 20  alkyl group, cycloalkyl group, aryl group, alkylaryl group, or arylalkyl group; (b 2 ) an aluminoxane having a formula (III):\n (R 12 ) 2 \u2014Al\u2014O\u2014[\u2014Al(R 13 )\u2014O-] m -Al\u2014(R 14 ) 2 \u2003\u2003(III) \n wherein R 12 , R 13  and R 14  each independently represent a hydrogen atom, a halogen atom, or a linear or branched C 1 -C 20  alkyl group, cycloalkyl group, or aryl group, optionally substituted with one or more silicon or germanium atoms; and m is an integer of 0 to 1000 (b 3 ) an aluminum organo-derivative compound that is partially hydrolyzed; and (b 4 ) a halogen-aluminum alkyl having a formula (IV) or (V):\n Al(R 15 ) p (X 3 ) 3-p \u2003\u2003(IV) \n Al 2 (R 15 ) q (X 3 ) 3-q \u2003\u2003(V) \n wherein p is 1 or 2; q is an integer of 1 to 5; each R 15  independently represents a linear or branched C 1 -C 20  alkyl group; and X 3  represents a chlorine or bromine atom.
