    • 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.
    • 本发明提供一种制备α-烯烃聚合物的方法,其特征在于在制备预活化催化剂中使用有机镁化合物。 除了各种优异的性能之外,所得聚合物具有特别高的刚性。 该方法包括使三价金属卤化物与二价金属化合物反应得到固体产物(I); 使该产物与有机镁化合物,电子给体(ED)和电子受体(EA)反应一次至10次,此时使用TiCl 4至少一次作为(EA)获得固体产物(II) ; 将该产物与有机铝化合物(OAl)和(ED)组合,然后将(II)和(OAl)或(II),(OAl)和(ED)的组合进行聚合处理, 在前一种组合的情况下,进一步加入(ED)以获得预活化的催化剂; 并在该催化剂存在下聚合α-烯烃。
