    Abstract: A catalyst component for olefin (co)polymerization, and in particular for the preparation of LLDPE, comprising Mg, Ti, halogen and an electron donor compound (ED) belonging to ethers, esters, amines, ketones, or nitriles, characterized in that the molar ratio Mg/Ti is higher than 5, and the molar ratio ED/Ti is higher than 3.5. The said catalyst components display a homogeneous distribution of the comonomer in and among the copolymer chains.

    Abstract: 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.

    Abstract: The present invention relates to a process for the preparation of random copolymers of propylene with c2-c10 alpha-olefins, carried out in the presence of a catalyst comprising:A) A solid component comprising a titanium compound supported on mgcl2 in active form and an electron-donor compound;b) An alkyl-al compound, andc) An electron-donor compound selected from the group of 1,3-diethers.The copolymers obtained using the said process show, for an equivalent content of alpha-olefin, a lower content of xylene-soluble fractions when compared with the copolymers obtained with the catalysts of the prior art.
