摘要： A process for producing .alpha.-olefin polymers characterized by employing an organomagnesium compound in the preparation of a preactivated catalyst therefor is provided. The resulting polymers have particularly a higher rigidity in addition to various superior properties. The process comprises reacting a trivalent metal halide with a divalent metal compound to obtain a solid product (I); reacting this product with an organomagnesium compound, an electron donor (ED) and an electron acceptor (EA), once to 10 times, and at that time, using TiCl.sub.4 at least once as the (EA) to obtain a solid product (II); combining this product with an organoaluminum compound (OAl) and an (ED), and at that time, subjecting a combination of (II) and (OAl) or that of (II), (OAl) and (ED) to polymerization treatment with an .alpha.-olefin, and in the case of the former combination, further adding (ED), to obtain a preactivated catalyst; and polymerizing .alpha.-olefin(s) in the presence of this catalyst.

摘要： A method for producing .alpha.-olefin polymers which enables to control molecular weight distribution in a narrower range, with a higher yield and a higher crystallinity of products, is proposed. A catalyst used in said method is also proposed. The solid component of said catalyst is obtained by reacting a trivalent metal halide with a hydroxide, an oxide, a carbonate of a divalent metal, a double compound containing any of these compounds or a hydrate of a compound containing a divalent metal to produce a solid product (I); reacting one or more electron donors and one or more electron acceptors separately or simultaneously each in from one step 10 steps but by using TiCl.sub.4 as an acceptor at least in one step, with said solid product (I) to obtain a solid product (II); and then combining an organoaluminum compound and an electron donor with said solid product (II).

摘要： A method for producing .alpha.-olefin polymers is provided. According to this method, particularly the catalyst stability is improved, resulting in polymers having a higher crystallinity, a narrower range of molecular weight, improved shape of polymer particles with a higher yield per a solid product component and per a transition metal component of the catalyst. Said catalyst is obtained by reacting a trivalent metal halide with a hydroxide, an oxide, a carbonate of a divalent metal, a double compound containing any of these compounds or a hydrate of a compound containing a divalent metal to form a solid product (I); reacting said solid product with one or more electron donors and one or more electron acceptors separately or simultaneously each in one to 10 steps but using TiCl.sub.4 as said acceptor(s) in at least one step to obtain a solid product (II); and then combining said solid product (II) with an organoaluminum compound and an electron doner, but before being used in polymerization, at least one part or the whole of said catalyst components is subjected to a polymerization-treatment with an .alpha.-olefin in the coexistence of at least both of said solid product (II) and said organoaluminum compound to form a preliminarily activated catalyst.
