ABSTRACT:
A method for producing .alpha.-olefin polymers is provided. This method provides products having superior properties such as higher bulk density and uniform particle form which is close to sphere, with such an extremely higher catalyst efficiency that ash-removal step can be omitted without fear of coloring. The characteristic point of this method is in the improvement of conventional catalyst obtained by reacting a trivalent metal halide with a divalent metal hydroxide, oxide or carbonate or a double salt containing foregoing compounds or a hydrate of a compound containing a divalent metal to form a solid product (I), reacting an electron donor with said product (I), reacting the resulting product with a compound of transition metal of the 4th a or the 5th a group to form a final solid product and combining an organoaluminum compound with said final product,
