Abstract
PURPOSE: To prepare an α-olefin polymer having improved shape at a high catalyst efficiency, by polymerizing an α-olefin in the presence of a catalyst comprising a solid reaction product and an organoaluminum compound.
CONSTITUTION: A trivalent metal halide is reacted with a bivalent metal hydroxide, a carbonate, a double salt containing them, or a hydrated bivalent metal compound at 20W500°C for 30 minW50 hr to give a solid reaction product. 100 grams of the product is incorporated with 10W10,000 grams of a polysiloxane and 1W100 grams of a compound of transition metals selected from Group IV a or Va in an amount of 10W100 grams per 100 grams of the polysiloxane at -50W40°C, and reacted at 30W300°C for 10 minW30hr to give a solid reaction product (A). An α-olefin is polymerized in the presence of a catalyst comprising the solid product (A) and an organoaluminum compound at 30W150°C and a pressure of normal one to 50 kg/cm2.
