Definitions
- European published patent application 400333 describes elastoplastic polyolefin compositions obtained by sequential polymerization comprising:
- This invention provides an elastoplastic polyolefin composition comprising, in percent by weight (all percent amounts being by weight):
- the total quantity of copolymerized ethylene is preferably from 30% to 65% by weight, more preferably from 30% to 60% by weight, in particular from 30% to 55% by weight.
- compositions typically present at least one melt peak, determined by way of DSC, at a temperature higher than 120° C., but equal to or lower than 150° C., in particular of from 135 to 145° C.
- Polymerization times and temperatures are not critical and are advantageously in the range from 0.5 to 5 hrs, and from 50° C. to 90° 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.
- a diene conjugated or not, such as butadiene, 1,4-hexadiene, 1,5-hexadiene and ethylidene-norbornene-1.
- the diene when present is typically in an amount of from 0.5 to 10% by weight with respect to the weight of (B).
- compositions can be prepared with a sequential polymerization process carried out in at least two stages, one or more for the synthesis of the component (A), the other(s) for the synthesis of component (B).
- the polymerization in the subsequent stages occurs in the presence of the polymer obtained and the catalyst used in the preceding stage(s).
- the polymerization can occur in liquid phase, gas phase or liquid-gas phase.
- component (A) in a copolymerization stage using liquid propylene as diluent it is possible to prepare component (A) in a copolymerization stage using liquid propylene as diluent, and component (B) in the following copolymerization stage in gas phase, without intermediate stages except for the partial degassing of the propylene.
- both components (A) and (B) are prepared by operating the copolymerization in gas phase.
- the order in which the components are prepared is not critical.
- 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 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 stereospecific catalysts used in the polymerization comprise the product of the reaction between:
- 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 U.S. Pat. No. 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 R 1 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.
- R 1 and R 2 are preferably C1-C8 alkyl, cycloalkyl, aryl, arylalkyl and alkylaryl groups. Particularly preferred are the compounds in which R 1 and R 2 are selected from primary alkyls and in particular branched primary alkyls. Examples of suitable R 1 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.
- 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° 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-0 416 815 (Dow), EP-A-0 420 436 (Exxon), EP-A-0 671 404, EP-A-0 643 066 and WO 91/04257. These metallocene compounds may be used in particular to produce the component (B).
- compositions of the present invention can also contain additives, fillers and pigments commonly used for olefin polymers, such as, for example, nucleating agents, extension oils, mineral fillers, organic and inorganic pigments.
- the polyolefin compositions of the present invention find application particularly in the sheet extrusion, blow moulding and thermoforming 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.
- the solid catalyst component used in polymerization is a highly stereospecific Ziegler-Natta catalyst component supported on magnesium chloride, containing about 2.2% by weight of titanium and diisobutylphthalate as internal donor, prepared by analogy with the method described in Example 3 of European published patent application 395083.
- the solid catalyst component described above is contacted at ⁇ 5° C. for 5 minutes with aluminum triethyl (TEAL) and dicyclopentyldimethoxysilane (DCPMS), in a TEAL/DCPMS weight ratio equal to about 5 and in such quantity that the TEAL/solid catalyst component weight ratio be equal to 5.
- TEAL aluminum triethyl
- DCPMS dicyclopentyldimethoxysilane
- the catalyst system is then subjected to prepolymerization by maintaining it in suspension in liquid propylene at 25° C. for about 30 minutes before introducing it into the first polymerization reactor.
- a propylene copolymer (component (A)) is produced by feeding in a continuous and constant flow the prepolymerized catalyst system, hydrogen (used as molecular weight regulator) and propylene and ethylene in the gas state.
- hydrogen used as molecular weight regulator
- the polypropylene copolymer produced in the first reactor is discharged in a continuous flow and, after having been purged of unreacted monomers, is introduced, in a continuous flow, into a second gas phase polymerization reactor, together with quantitatively constant flows of hydrogen, ethylene and propylene in the gas state.
- the polymer coming from the second reactor is discharged in a continuous flow and, after having been purged of unreacted monomers, is introduced, in a continuous flow, into a third gas phase polymerization reactor, together with quantitatively constant flows of hydrogen, propylene and ethylene in the gas state.
- the polymer particles exiting the third reactor are subjected to a steam treatment to remove the reactive monomers and volatile substances, and then dried.
- the polymer particles are mixed with usual stabilisers in a twin screw extruder Berstorff ZE 25 (length/diameter ratio of screws: 33) and extruded under nitrogen atmosphere in the following conditions:
- Rotation speed 250 rpm; Extruder output: 6-20 kg/hour; Melt temperature: 200-250° C.
