Abstract
PURPOSE: To obtain a polyolefin by gas phase polymerization in a stable and simple way, by the use of a highly active catalyst obtained by bringing into contact, with an α-olefin, of a catalyst consisting of an organometallic compound and a mixture containing Mg and Ti (or V) in the presence of a liquid hydrocarbon.
CONSTITUTION: First, a hyghly active catalyst is prepared by bringing into contact, with an α-olefin (pref. a 3W8C α-olefin), of a catalyst consisting of an organometallic compound like triisobutylaluminum and a solid material carried with a Ti- or V-compound on a Mg type carrier such as anhydrous magnesium chloride, in the presence of a liquid hydrocarbon such as n-hexane, pref. at 0W110°C for 1 minuteW 24 hrs. The amount of the original catalyst is pref. 1W500g per g of the solid material. Using the catalyst obtained, ethylene is polymerized or copolymerized with an α-olefin pref. at 50W100°C under a pressure of 2W60kg/cm2 by a gas phase polymerization method to obtain the objective polyolefin.
