Abstract
The present invention provides a novel catalyst system which can be preferably used in the trimerization, oligomerization reaction or polymerization reaction of an olefin, and a method for the trimerization, oligomerization or polymerization reaction of an olefin, which comprises using the catalyst system. A catalyst system obtained by contacting the following components (A) to (C): (A) a chromium compound, (B) an imine compound, and (C) a metal alkyl compound, and a method for the trimerization, oligomerization or polymerization reaction of an olefin, which comprises using the catalyst system are disclosed.
Claims8
A catalyst system obtained by contacting the following components (A) to (C):
- (A) a chromium compound,
- (B) an imine compound having a double bond between carbon and nitrogen, wherein the component (B) is a diimine compound represented by the following general formulae (1) or (2):
- ##STR4## wherein R.sup.1 to R.sup.12 represent a hydrogen atom or a hydrocarbon group, and the hydrocarbon group is an alkyl group having 1 to 30 carbon atoms, a cycloalkyl group having 3 to 30 carbon atoms, a cyclopentadienyl group having 5 to 30 carbon atoms, an aryl group having 6 to 30 carbon atoms, an alkylaryl group having 6 to 30 carbon atoms or an arylalkyl group having 6 to 30 carbon atoms and these groups may be groups containing a halogen atom, an oxygen atom, a nitrogen atom, a silicon atom, or a sulfur atom:
- at last two of R.sup.1 to R.sup.6 and R.sup.7 to R.sup.12 may bond to each other to form a ring:
- and m and n represent an integer of 0 to 6, and
- (C) a metal alkyl compound.
