    摘要: The present invention provides a method for producing homo- and co-polymers of ethylene, or more particularly a method for producing homo- and co-polymers of ethylene in the presence of (a) a solid titanium catalyst produced by means of preparing a magnesium solution by contact-reacting a halogenated magnesium compound with alcohol; reacting thereto an ester compound having at least one hydroxyl group and a silicon compound having at least one alkoxy group; and adding a mixture of a titanium compound and a silicon compound; (b) organometallic compounds of Group II or III of the Periodic Table; and (c) a cyclic nitrogen compound. The catalyst for homo- and co-polymerization of ethylene, produced according to the present invention, is of high activity, and the polymers produced by the method of the present invention by using said catalyst have the advantages of having high bulk density and narrow molecular weight distribution.

    摘要: The invention provides a process for producing polypropylene and/or random copolymers of propylene type using a stereoregular catalyst which comprises a titanium-containing solid catalyst component (A), an organoaluminum compound (B) and if required an organosilicon compound (C), wherein

    [I] before carrying out homopolymerization of propylene or random copolymerization of propylene with an α-olefin other. than propylene, the above component (A), an organoaluminum compound (B') and if required an organosilicon compound (C') are used, and a small amount of propylene or ethylene and/or an α-olefin of 4 - 20 carbon atoms for pre-activation treatment is supplied to the above component (A), and
    [II] a catalyst which is prepared by adding an organosilicon compound (C") to the pre-activated stereoregular catalyst in a molar ratio of 0.1 - 50 as Si/Ti, is used to produce polypropylene (propylene homopolymer) or propylene random copolymers (propylene-α-olefin random copolymers) with lesser formation of lump and string-like irregular shape polymers.
