- Polymerization times and temperatures are not critical and are advantageously in the range from 0.5 to 5 hrs, and from 50 0 C to 90 0 C respectively.
- component (B) The copolymerization of ethylene and propylene or other alpha-olefin(s), examples of which are given above for component (A), or combinations thereof, to form component (B) can occur in the presence of a diene, conjugated or not, such as butadiene, 1,4-hexadiene, 1,5-hexadiene and ethylidene-norbornene-1.

- the pressure of a single stage, if carried out in liquid monomer is the one which competes with the vapor pressure of the liquid propylene at the operating temperature used, and is modified by the overpressure of the monomer(s) and the hydrogen used as molecular weight regulator, and possibly by the vapor pressure of the small quantity of inert diluent used to feed the catalyst mixture.
- the polymerization pressure if done in liquid phase, indicatively can be from 5 to 30 atm.
- the residence times relative to the two or more stages depend on the desired ratio between component (A) and (B), and are usually from 15 min. to 8 hours.
- the said polymerization processes are generally carried out in the presence of stereospecific Ziegler-Natta catalysts supported on magnesium dihalides.
- the said stereospecific catalysts used in the polymerization comprise the product of the reaction between:
- Said catalysts are preferably capable of producing homopolymer polypropylene having an isotactic index higher than 90%.
- the solid catalyst component (1) contains as electron-donor a compound generally selected among the ethers, ketones, lactones, compounds containing N, P and/or S atoms, and mono- and dicarboxylic acid esters.
- Catalysts having the above mentioned characteristics are well known in the patent literature; particularly advantageous are the catalysts described in US patent 4,399,054 and European patent 45977. Particularly suited among the said electron-donor compounds are phthalic acid esters and succinic acid esters.
- Suitable succinic acid esters are represented by the formula (I):
- radicals Ri and R 2 are a C1-C20 linear or branched alkyl, alkenyl, cycloalkyl, aryl, arylalkyl or alkylaryl group, optionally containing heteroatoms;
- the radicals R 3 to R 6 equal to or different from each other, are hydrogen or a C1-C20 linear or branched alkyl, alkenyl, cycloalkyl, aryl, arylalkyl or alkylaryl group, optionally containing heteroatoms, and the radicals R 3 to R 6 which are joined to the same carbon atom can be linked together to form a cycle.
- Ri and R 2 are preferably C1-C8 alkyl, cycloalkyl, aryl, arylalkyl and alkylaryl groups. Particularly preferred are the compounds in which Ri and R 2 are selected from primary alkyls and in particular branched primary alkyls. Examples of suitable Ri and R 2 groups are methyl, ethyl, n-propyl, n-butyl, isobutyl, neopentyl, 2-ethylhexyl. Particularly preferred are ethyl, isobutyl, and neopentyl.
- R 3 to R 5 are hydrogen and R 6 is a branched alkyl, cycloalkyl, aryl, arylalkyl and alkylaryl radical having from 3 to 10 carbon atoms.
- Another preferred group of compounds within those of formula (I) is that in which at least two radicals from R 3 to R 6 are different from hydrogen and are selected from C1-C20 linear or branched alkyl, alkenyl, cycloalkyl, aryl, arylalkyl or alkylaryl group, optionally containing heteroatoms.
- Particularly preferred are the compounds in which the two radicals different from hydrogen are linked to the same carbon atom.
- the compounds in which at least two radicals different from hydrogen are linked to different carbon atoms that is R 3 and R 5 or R 4 and R 6 are particularly preferred.

- cocatalysts (2) one preferably uses the trialkyl aluminum compounds, such as Al- triethyl, Al-triisobutyl and Al-tri-n-butyl.
- the electron-donor compounds (3) that can be used as external electron-donors (added to the Al-alkyl compound) comprise the aromatic acid esters (such as alkylic benzoates), heterocyclic compounds (such as the 2,2,6,6-tetramethylpiperidine and the 2,6- diisopropylpiperidine), and in particular silicon compounds containing at least one Si-OR bond (where R is a hydrocarbon radical).
- aromatic acid esters such as alkylic benzoates
- heterocyclic compounds such as the 2,2,6,6-tetramethylpiperidine and the 2,6- diisopropylpiperidine
- silicon compounds containing at least one Si-OR bond where R is a hydrocarbon radical
- the catalysts may be precontacted with small quantities of olefin (prepolymerization), maintaining the catalyst in supension in a hydrocarbon solvent, and polymerizing at temperatures from room to 60 0 C, thus producing a quantity of polymer from 0.5 to 3 times the weight of the catalyst.
- the operation can also take place in liquid monomer, producing, in this case, a quantity of polymer up to 1000 times the weight of the catalyst.
- Another class of suitable catalysts are the so-called constrained geometry catalysts, as described in EP-A-O 416 815 (Dow), EP-A-O 420 436 (Exxon), EP-A-O 671 404, EP-A-O 643 066 and WO 91/04257. These metallocene compounds may be used in particular to produce the component (B).

- the polyolefin compositions of the present invention find application particularly in the sheet extrusion, blow moulding and thermo forming fields.
- the percent by weight of polymer insoluble in xylene at room temperature is considered the isotacticity index of the polymer. This value corresponds substantially to the isotacticity index determined by extraction with boiling n-heptane, which by definition constitutes the isotacticity index of polypropylene.
