Abstract: A process for the preparation of a solid catalyst component for the polymerization of CH2═CHR olefins, wherein R is hydrogen or hydrocarbyl radical with 1-12 carbon atoms, made from or containing a Ti compound on a Mg chloride based support, including the steps of (a) reacting a Mg based compound with a liquid medium made from or containing a Ti compound, at a temperature ranging from 0 to 150° C., thereby yielding solid particles; and (b) suspending the solid particles coming from step (a) in a liquid medium made from or containing hydrocarbons at a temperature ranging from 10 to 100° C., wherein step (a) or (b) is carried out in the presence of 0.2 to 20.0% by weight, with respect to the amount of Mg compound, of particles of a solid compound containing more than 50% by weight of SiO2 units and having average particle size from 1 to 100 μm.

Abstract: The present disclosure relates to a process for the preparation of a porous propylene carried out in the presence of a catalyst system comprising (a) a Ziegler-Natta catalyst containing at least two electron donor compounds, one of which is present in an amount from 50 to 90% by mol with respect to the total amount of donors and selected from succinates, and the other being selected from 1,3 diethers, (b) an aluminum alkyl and comprising the following steps: i) contacting the catalyst components (a) and (b) for a period of time ranging from 1 to 60 minutes, at a temperature ranging from 35 to 55° C.; optionally, ii) pre-polymerizing with one or more olefins of formula CH2═CHR, where R is H or a C1-C10 hydrocarbon group, up to forming amounts of polymer from about 0.1 up to about 1000 g per gram of solid catalyst component (a); and iii) polymerizing propylene in the optional presence of minor amounts of ethylene and/or C4-C10 alpha olefins for producing the porous propylene (co)polymer.
