| titleOfInvention | Process for preparing conjugated diene (co) polymers in the presence of a catalytic system comprising a pyridyl iron (III) complex |
| abstract | Process for preparing (co)polymers of conjugated diene comprising polymerizing at least one conjugated diene in the presence of a catalytic system comprising: (a) at least one pyridyl iron (III) complex having the general formula (I) or ( II): **(See formula)** in which: - R1, R2, R3 and R4, identical or different, represent a hydrogen atom; or are selected from C1-C20, preferably C1-C15, linear or branched, optionally halogenated alkyl groups, optionally substituted cycloalkyl groups, optionally substituted aryl groups; - R5 represents a hydrogen atom, or is selected from C1-C20, preferably C1-C15, linear or branched, optionally halogenated alkyl groups, optionally substituted cycloalkyl groups, optionally substituted aryl groups; - X, identical or different, represents a halogen atom such as chlorine, bromine, iodine; or are selected from C1-C20, preferably C1-C15, linear or branched alkyl groups, -OCOR6 groups or -OR6 groups in which R6 is selected from C1-C20, preferably C1-C15, linear or branched alkyl groups ; - n is 3; (b) at least one cocatalyst selected from organic aluminum derivatives, preferably from: (b1) aluminum compounds having the general formula (III): Al(R7)(R8)(R9) (III) in which R7 represents a hydrogen atom, or is selected from linear or branched C1-C20 alkyl groups, cycloalkyl groups, aryl groups, alkylaryl groups, arylalkyl groups, alkoxy groups; R8 and R9, identical or different, are selected from linear or branched C1-C20 alkyl groups, cycloalkyl groups, aryl groups, alkylaryl groups, arylalkyl groups; (b2) aluminoxanes having the general formula (IV): (R10)2-Al-O-[-Al(R11)-O-]m-Al-(R12)2 (IV) in which R10, R11 and R12, identical or different, represent a hydrogen atom, or a halogen atom such as chlorine, bromine, iodine, fluorine, or are selected from linear or branched C1-C20 alkyl groups, cycloalkyl groups, aryl groups, said groups that are optionally substituted with one or more silicon or germanium atoms; and m is an integer ranging from 0 to 1000; (b3) partially hydrolyzed organic aluminum derivatives; (b4) haloaluminum alkyls having the general formula (V) or (VI): Al(R13)p(X')3-p (V) Al2(R13)q(X')3-q (VI) in where p is 1 or 2; q is an integer ranging from 1 to 5; R13, identical or different, are selected from linear or branched C1-C20 alkyl groups; X' represents a chlorine or bromine atom, preferably chlorine; provided that said cocatalyst (b) is not selected from organic derivatives of boron. |
