    • The invention relates to a process for the polymerization of olefins in which at least one olefin is placed in contact with a catalytic system comprising: a) a catalytic solid comprising magnesium, at least on transition metal selected from the group consisting of titanium and zirconium and halogen, prepared by successively: - reacting, in a first step (1), at least one magnesium compound (M) chosen from oxygen-containing organic magnesium compounds with at least on compound (T) selected from the group consisting of oxygen-containing or halogen-containing tetravalent titanium and zirconium compounds, until a liquid complex is obtained; - treating, in a second step (2), the said liquid complex with an electron donor (ED); - treating, in a third step (3), the complex obtained in step (2) with a halogen-containing aluminic compound of formula A1R n X 3-n , in which R is a hydrocarbon radical comprising up to 20 carbon atoms, X is halogen and n is less than 3, and B) an organometallic compound of a metal chosen from lithium, magnesium, zinc, aluminum or tin, wherein the complex obtained in step (2) of the preparation of the catalytic solid (a) is a substantially solid complex and the electron donor (ED) is a benzoyl halide.
    • 本发明涉及一种烯烃聚合方法,其中至少一种烯烃与催化体系接触,所述催化体系包括:a)至少在选自钛和锆的过渡金属上的至少含有镁的催化固体,以及 卤素,通过以下步骤连续制备: - 在第一步骤(1)中使至少一种选自含氧有机镁化合物的至少一种选自以下的化合物(T)的镁化合物(M) 或含卤素的四价钛和锆化合物,直到获得液体络合物; 在第二步(2)中,用电子给体(ED)处理所述液体络合物; 在第三步骤(3)中,用式AlRnX 3-n的含卤素的铝酸盐化合物处理步骤(2)中得到的络合物,其中R是包含至多20个碳原子的烃基,X是卤素和 n小于3,B)选自锂,镁,锌,铝或锡的金属的有机金属化合物,其中步骤(2)中获得的制备催化剂固体(a)的络合物基本上是固体 络合物和电子给体(ED)是苯甲酰卤。
