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.

Abstract: PURPOSE: Provided is a catalyst system, with which polyolefin wax having increased wax content and excellent physical properties can be prepared under mild reaction conditions. CONSTITUTION: The catalyst system for preparing polyolefin wax comprises a main catalyst containing a transition metal component, a calixarene ligand and a halogen component, and a co-catalyst containing an organoaluminum compound. In the main catalyst, the transition metal component is selected from the group consisting of chrome, titanium, vanadium and zirconium. The calixarene ligand is one selected from the group consisting of para-butylcalix£4|arene, parabutylcalix£5|arene, parabutylcalix£6|arene, parabutylcalix£8| arene and derivatives thereof, or a combination thereof. Additionally, the halogen component is chlorine or bromine.
