Abstract
PURPOSE: To produce an olefin polymer having wide molecular-weight distribution and good moldability with high activity, by a method wherein the olefin is polymerized in the presence of a catalyst composed of a specified solid catalyst component and an organoaluminum cpd.
CONSTITUTION: A mixt. of (a) a Ti cpd selected from halides and org. oxygenated cpd. of Ti, (b) a V cpd. selected from halides and org. oxygenated cpd. of V, and (c) a Hf cpd. selected from halides and org. oxygenated cpd. of Hf is reacted with (d) an organoaluminum bromide such as Al(C2H5)Br2 or Al(CH3)Br2 in the presence or absence of an inert hydrocarbon solvent at a temp. of 0W200°C to obtain (A) a solid catalyst component. An olefin is polymerized in the presence of a catalyst composed of (A) the solid catalyst component and (B) organoaluminum cpd. of formula AlRk 8X3-k 7 (wherein R8 is alkyl, aryl, cycloalkyl gp.; X7 is halogen; k is 1W3).
