    • A method for producing a stereospecific polyolefin in the presence of a catalyst comprising a transition metal compound and an organometallic compound, wherein a catalyst system is used which comprises (A) a solid catalyst component prepared by reacting a homogeneous solution containing (i) at least one member selected from the group consisting of metal magnesium and a hydroxylated organic compound, and oxygen-containing organic compounds of magnesium, (ii) an oxygen-containing organic compound of aluminum and (iii) an oxygen-containing organic compound of titanium, with (iv) at least one aluminum halide compound to obtain a solid product, and further reacting to this solid product, (v) an electron-donative compound and (vi) a titanium halide compound, (B) at least one member selected from the group consisting of organometallic compounds of Groups IA, IIA, IIB, IIIB and IVB of the Periodic Table, and (C) an oxygen-containing organic compound of silicon which has no aromatic substituent and which has at least one hydrocarbon group containing a secondary or tertiary carbon directly bonded to a silicon atom.
    • 在含有过渡金属化合物和有机金属化合物的催化剂存在下制备立体有择性聚烯烃的方法,其中使用催化剂体系,其包括(A)固体催化剂组分,其通过使含有(i)至少 选自金属镁和羟基化有机化合物的一种成员和镁的含氧有机化合物,(ii)铝的含氧有机化合物和(iii)含氧有机化合物的钛,与 (iv)至少一种卤化铝化合物,以获得固体产物,并进一步与该固体产物反应,(v)给电子化合物和(vi)卤化钛化合物,(B)至少一种选自 由元素周期表的IA,IIA,IIB,IIIB和IVB族的有机金属化合物组成的组,和(C)不含芳族取代基的硅的含氧有机化合物 并且其具有至少一个含有直接键合到硅原子上的仲或叔碳的烃基。
