    • A catalyst for polymerization of olefin comprising: (I) solid catalyst obtained by reacting hydrocarbon solvent-soluble organomagnesium compound (a) represented by the formula (wherein R and R are the same or different and each represents a secondary tertiary-alkyl group containing 4-6 carbon atoms, X represents a negative group containing O, N, or S, p and q each represents a number of 0-2, and r represents a number of 0-1, with p+q+r being equal to 2) with titanium or vanadium compound (b) containing at least one halogen atom; and (II) organometallic compound. The catalyst has a high activity, and is uniform and highly dense. Thus, it is suited for continuous polymerization of olefin, and permits elimination of the step of removing the catalyst after polymerization reaction. A catalyst for polymerization of olefin obtained by replacing the above-described solid catalyst (I) by solid catalyst (I') obtained by further reacting solid catalyst (I) with compound (b) or with organic or inorganic compound (c) of aluminum, silicon, tin, or antimony, and a catalyst prepared by further incorporating therein halogenated hydrocarbon (III), provides polyolefins with a wide molecular weight distribution.
    • 一种烯烃聚合用催化剂,其特征在于,含有:(I)通过使由式(IMA)表示的烃类溶剂可溶性有机镁化合物(a)(其中R 1和R 2相同或不同, 表示含有4-6个碳原子的仲叔烷基,X表示含有O,N或S的负基团,p和q各自表示0-2的数,r表示0-1的数,与 p + q + r等于2)与含有至少一个卤素原子的钛或钒化合物(b) 和(II)有机金属化合物。 催化剂活性高,均匀高密度。 因此,适用于烯烃的连续聚合,可以消除聚合反应后除去催化剂的工序。 通过将固体催化剂(I)与化合物(b)进一步反应或与铝的有机或无机化合物(c)进一步反应获得的固体催化剂(I')代替上述固体催化剂(I)而获得的烯烃聚合催化剂 ,硅,锡或锑,以及通过进一步掺入卤代烃(III)制备的催化剂,提供具有宽分子量分布的聚烯烃。
