Abstract
PURPOSE: To prepare a crystalline poly-1-butene having a high bulk density and giving a high slurry concentration, by prepolymerizing a small amount of an α-olefin, etc. at a specific temperature in the presence of a catalyst comprising a specific titanium composite and an organometallic compound and thereafter carrying out polymerization.
CONSTITUTION: In the presence of a catalyst system comprising (A) a titanium composite consisting essentially of magnesium, titanium, a halogen and an electron donor and prepared by reacting a magnesium compound (e.g. magnesium chloride) with a titanium compound (e.g. titanium tetrachloride) and an electron donor (e.g. ethyl benzoate), and (B) an organometallic compound of a IWIII group metal in the periodic table (e.g. triethylaluminum), a small amount of 1-butene or an α-olefin (e.g. ethylene) is prepolymerized at <30°C or at ≤80°C, respectively, and thereafter 1-butene is polymerized at 30W48°C.
