Abstract: PURPOSE: Provided are catalyst and a method for ethylene oligomerization. The method can produce olefin with high reaction activity and selectivity by using pyridine derivatives as ligand in catalyst comprised of Cr compound, ligand and alkyl aluminum. CONSTITUTION: The catalyst is consisted of Cr compounds, 3-coordinative pyridine structure ligand, and alkyl aluminum, wherein the ligand is expressed as the formula 1, where R is hydrogen or C1-C6 alkyl group, -X1 and -X2 are =N and -P, respectively, wherein if the X1 or X2 is N(nitrogen), n is 1 whereas if X1 or X2 is P, n is 2, and wherein Ph is phenyl group or replaced phenyl group, and if the Ph is replaced phenyl group, the substituent is selected from a group being consisted of C1-C6 alkyl group and C1-C6 alkoxy group.

Abstract: PURPOSE: Provided is a chrome-calixarene-organoaluminum catalyst which has excellent catalytic activity and is stable in polymerizing olefin. The catalyst is simple to synthesize and reproducible. It can be used in making specific polymers different from polymers made by usual Ziegler-Natta or chrome supported catalysts in molecular weight distribution and the degree of crystallinity and unsaturation. CONSTITUTION: The catalyst comprises 1 mole of chrome(III) compound, 0.5-2 moles of calixarene compound and 10-1000 moles of organic aluminum compound. The polymerization is carried out with the catalyst at 30-200deg.C under 3-50 atm and the catalyst is either added with molecular chrome-calixarene and organic aluminum respectively or in one shot of the mixed component.
