    摘要： Catalyst components for the polymerization of olefins comprising Mg, Ti, halogen and 1,3-diethers as internal donors having an improved balance of properties in terms of activity and morphological stability are obtained by a process comprising: (A) A first step comprising reacting an adduct of formula MgCl2(ROH)n, where R is a C1-C10 alkyl group, and n is from 0.5 to 6, with a titanium compound having at least a Ti—Cl bond at a reaction temperature ranging from 0° C. to 80° C.; (B) A subsequent step comprising contacting the solid product obtained in (A) with an electron donor ED selected from 1,3 diethers with a titanium compound having at least a Ti—Cl bond at a temperature higher than 80° C.; and (C) A subsequent step comprising reacting the solid product coming from (B) with a titanium compound having at least a Ti—Cl bond at a temperature higher than 80° C.

    摘要： The present invention relates to catalyst components for the polymerization of olefins having Mg, Ti, halogen and at least two internal electron donor compounds, said catalyst components characterized by the fact that at least one of the electron donor compounds is selected from ethers containing two or more ether groups which are further characterized by the formation of complexes with anhydrous magnesium dichloride in an amount less than 60 mmoles per 100 g of MgCl2 and by the failure of entering into substitution reactions with TiCl4 or by reacting in that way for less than 50% by moles, and at least another electron donor compound selected from esters of mono or polycarboxylic acids. Said catalyst components are able to produce propylene polymers which, for high values of xylene insolubility, show a broad range of isotacticity.
