Abstract: The present disclosure relates to a porous solid adduct comprising magnesium chloride and ethanol, characterized by a relationship between the content of alcohol, average pore radius and amount of porosity deriving from pores with radii of 100-1000 nm, and catalyst components produced therefrom that are capable of producing polyolefins with increased porosity.

Abstract: A process for preparing a catalyst component made from or containing Mg, Ti, and at least an electron donor compound (ID), including the steps of: (a) reacting a Mg based compound with a Ti compound, having at least a Ti—Cl bond, in an amount such that the Ti/Mg molar ratio is greater than 3 and at a temperature ranging from 0 to 150° C., thereby yielding an intermediate solid catalyst component containing Mg and Ti; and (b) contacting the intermediate solid catalyst component with a gaseous stream containing the electron donor compound (ID) in a gaseous dispersing medium, thereby yielding a final solid catalyst component having an ID/Ti molar ratio ranging from 0.5:1 to 20:1.

Abstract: Solid adducts comprising MgCl2 and an alcohol ROH in which R is a C1-C20 hydrocarbon group, in which the amount of alcohol ranges from higher than 42% to 60% by weight and the porosity determined with Hg method due to pores up to 1 μm and expressed in cm3/g, is such that the value of its ratio with the amount of alcohol in percentage falls above the straight line defined by the equation y=−0.0158x+1.03 in which y is the porosity of the adduct and x is the alcohol percentage by weight.
