    Abstract: 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 being 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 CH 2 =CHR, where R is H or a C 1 -C 10 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 C 4 -C 10 alpha olefins producing said porous propylene (co)polymer.

    Abstract: A solid catalyst component for the polymerization of olefins CH 2 =CHR in which R is hydrogen or a hydrocarbon radical with 1-12 carbon atoms, comprising Mg, Ti, Bi, halogen and an electron donor obtained from a process comprising: (a) dissolving a Mg(OR) 2 compound where R groups, equal or different to each other, are C 1 -C 15 hydrocarbon groups optionally containing a heteroatom selected from O, N and halogen, in an organic liquid medium in order to have a liquid mixture; (b) contacting the above mixture (a) with Ti Cl 4 obtaining a liquid mixture not containing solid phase, and (c) subjecting the liquid mixture (b) to conditions such that solid catalyst particles are formed, said process being characterized by the fact that (i) a Bi compound and (ii) a bidentate electron donor compound is present in one or more of steps (a) to (c) and/or contacted with the solid catalyst particles obtained from (c).
