Реферат: ABSTRACT OF THE DISCLOSURE Catalyst components which comprise the reaction product of a Ti compound and a Mg dihalide and which are in the form of spherical particles having an average diameter of 1 to 100 microns, a surface area of 300 to 500 m2/g, and a porosity of 0.3 to 0.4 cc/g are disclosed, as are catalysts also in the form of spherical particles prepared therefrom and useful in the polymeriztion of ethylene and of alpha-olefins CH2 = CHR in which R is alkyl radical having from 1 to 6 carbon atoms, and the polymerization of the alpha-olefins therewith.
Components of catalysts useful for the polymerization of alpha-olefins, and catalysts prepared therefrom
