| titleOfInvention | Method for producing polyisoprene having mainly alternating CIS-1,4-ALT-3,4 structure in the presence of a catalyst system containing a pyridyl iron complex |
| abstract | It mainly relates to a method for producing polyisoprene having an alternating cis -1,4- alt -3,4 structure, the method comprising polymerizing isoprene in the presence of a catalyst system comprising: (a) at least one pyridyl iron complex having the following formula (I): In the above formula (I): -R 1 is selected from linear or branched C 1 -C 20 , preferably C 1 -C 15 , alkyl groups, optionally substituted cycloalkyl groups, optionally substituted aryl groups; -R 2 is selected from linear or branched C 1 -C 10 , preferably C 1 -C 3 , alkyl groups; -X is the same as or different from each other and represents a halogen atom such as chlorine, fluorine, iodine; Or they are selected from linear or branched C 1 -C 20 , preferably C 1 -C 15 , alkyl groups, -OCOR 3 groups or -OR 3 groups, wherein R 3 is linear or branched C 1 -C 20 , Preferably C 1 -C 15 , selected from an alkyl group; -n is 2 or 3; (b) at least one cocatalyst selected from organo-derivative compounds of aluminum, preferably selected from: (b1) aluminoxane having the following formula (II): In the above formula (II), R 4 , R 5 and R 6 are the same as or different from each other, and represent a hydrogen atom or a halogen atom such as chlorine, fluorine, iodine, or fluorine; Or they are selected from linear or branched C 1 -C 20 alkyl groups, cycloalkyl groups, aryl groups, and the groups are optionally substituted with one or more silicon or germanium atoms; m is an integer ranging from 0 to 1000; (b2) an aluminum compound having the following formula (III): In the above formula (III), R 7 represents a hydrogen atom, or is selected from a linear or branched C 1 -C 20 alkyl group, a cycloalkyl group, an aryl group, an alkylaryl group, an arylalkyl group, and an alkoxy group; R 8 and R 9 are the same as or different from each other, and are selected from a linear or branched C 1 -C 20 alkyl group, a cycloalkyl group, an aryl group, an alkylaryl group, an arylalkyl group; Here, the molar ratio between the aluminum present in the cocatalyst and the iron present in the pyridyl iron complex having the formula (I) is in the range of 5 to 60, preferably 8 to 55. |
