titleOfInvention | Process for preparing conjugated diene (co)polymers in the presence of a catalytic system comprising a pyridyl iron (III) complex |
abstract | A process for preparing conjugated diene (co)polymers comprising polymerizing at least one conjugated diene in the presence of a catalytic system comprising: (a) at least one pyridyl iron (III) complex having general formula (I) or (II): wherein: —R 1 , R 2 , R 3 and R 4 , identical or different, represent a hydrogen atom; or are selected from linear or branched, optionally halogenated C 1 -C 20 , preferably C 1 -C 15 , alkyl groups, optionally substituted cycloalkyl groups, optionally substituted aryl groups; —R 5 represents a hydrogen atom, or is selected from linear or branched, optionally halogenated C 1 -C 20 , preferably C 1 -C 15 , alkyl groups, optionally substituted cycloalkyl groups, optionally substituted aryl groups; —X, identical or different, represent a halogen atom such as, for example, chlorine, bromine, iodine; or are selected from linear or branched C 1 -C 20 , preferably C 1 -C 15 , alkyl groups, —OCOR 6 groups or —OR 6 groups wherein R 6 is selected from linear or branched C 1 -C 20 , preferably C 1 -C 15 , alkyl groups. —n is 3; (b) at least one co-catalyst selected from organo-aluminum derivatives, preferably from: (b 1 ) aluminum compounds having general formula (III): Al(R 7 )(R 8 )(R 9 ) (IIl) wherein R 7 represents a hydrogen atom, or is selected from linear or branched C 1 -C 20 alkyl groups, cycloalkyl groups, aryl groups, alkylaryl groups, arylalkyl groups, alkoxy groups; R 8 and R 9 , identical or different, are selected from linear or branched C 1 -C 20 alkyl groups, cycloalkyl groups, aryl groups, alkylaryl groups, arylalkyl groups; (b 2 ) aluminoxanes having general formula (IV): (R 10 ) 2 —Al—O—[-AI(R 11 )—O-] m -AI-(R 12 ) 2 (IV), wherein R 10 , R 11 and R 12 , identical or different, represent a hydrogen atom, or a halogen atom such as chlorine, bromine, iodine, fluorine; or are selected from linear or branched C 1 -C 20 alkyl groups, cycloalkyl groups, aryl groups, said groups being optionally substituted with one or more silicon or germanium atoms; and m is an integer ranging from 0 to 1000; (b 3 ) partially hydrolyzed organo-aluminum derivatives; (b 4 ) haloaluminum alkyls having general formula (V) or (VI): AI(R 13 ) p (X′) 3-p (V) AI 2 (R 13 ) q (X′) 3-q (VI) wherein p is 1 or 2; q is an integer ranging from 1 to 5; R 13 , identical or different, are selected from linear or branched C 1 -C 20 alkyl groups; X′ represents a chlorine or bromine atom, preferably chlorine; provided that said co-catalyst (b) is not selected from organo-boron derivatives. |
