  • the support may also be able to take the place of a Lewis or Bronsted acid, for instance an acidic clay such as montmorillonite, if needed.
  • These "heterogeneous" catalysts may be used to catalyze polymerization in the gas phase or the liquid phase.
  • gas phase is meant that a gaseous olefin is transported to contact with the catalyst particle.
  • the polymerization catalysts and/or polymer formed is in the form of a fluidized bed.
  • olefinic oligomers and polymers are made. They may range in molecular weight from oligomeric POs (polyolefins), to lower molecular weight oils and waxes, to higher molecular weight POs.
  • One preferred product is a POs with a degree of polymerization (DP) of about 10 or more, preferably about 40 or more.
  • DP is meant the average number of repeat units in a PO molecule.
  • the POs made by the processes described herein are useful in many ways. For instance if they are thermoplastics, they may be used as molding resins, for extrusion, films, etc. If they are elastomeric, they may be used as elastomers. If they contain functionalized monomers such as acrylate esters or other polar monomers, they are useful for other purposes, see for instance previously incorporated US 5,880,241.
  • the POs may have varying properties. Some of the properties that may change are molecular weight and molecular weight distribution, crystallinity, melting point, and glass transition temperature. Except for molecular weight and molecular weight distribution, branching can affect all the other properties mentioned, and branching may be varied (using the same nickel compound) using methods described in previously incorporated US 5,880,241.
  • blends of distinct polymers may have advantageous properties compared to "single" polymers.
  • polymers with broad or bimodal molecular weight distributions may be melt processed (be shaped) more easily than narrower molecular weight distribution polymers.
  • Thermoplastics such as crystalline polymers may often be toughened by blending with elastomeric polymers.
  • the transition metal containing polymerization catalyst disclosed herein can be termed the first active polymerization catalyst.
  • a second active polymerization catalyst (and optionally one or more others) is used in conjunction with the first active polymerization catalyst.
  • the second active polymerization catalyst may be another late transition metal catalyst, for example as described in previously incorporated US 5,880,241 , US 6,060,569 and US 6,174,795, as well as US 5,714,556 and US 5,955,555 which are also incorporated by reference herein as if fully set forth.
  • catalysts may also be used for the second active polymerization catalyst.
  • so-called Ziegler-Natta and/or metallocene-type catalysts may also be used.
  • These types of catalysts are well known in the polyolefin field, see for instance Angew. Chem., Int. Ed. Engl., vol. 34, p. 1143-1170 (1995), EP-A-0416815 and US 5,198,401 for information about metallocene-type catalysts, and J. Boor Jr., Ziegler- Natta Catalysts and Polymerizations, Academic Press, New York, 1979 for information about Ziegler-Natta-type catalysts, all of which are hereby included by reference.
  • the first olefin(s) (olefin(s) polymerized by the first active polymerization catalyst) and second olefin(s) (the monomer(s) polymerized by the second active polymerization catalyst) are identical.
  • the second olefin may also be a single olefin or a mixture of olefins to make a copolymer.
  • the first active polymerization catalyst polymerizes one or olefins, a monomer that may not be polymerized by said second active polymerization catalyst, and/or vice versa. In that instance two chemically distinct polymers may be produced. In another scenario two monomers would be present, with one polymerization catalyst producing a copolymer, and the other polymerization catalyst producing a homopolymer.
  • the first active polymerization catalyst is described in detail above.
  • the second active polymerization catalyst may also meet the limitations of the first active polymerization catalyst, but must be chemically distinct. For instance, it may utilize a different ligand which differs in structure between the first and second active polymerization catalysts. In one preferred process, the ligand type and the metal are the same, but the ligands differ in their substituents.
  • two active polymerization catalysts include systems in which a single polymerization catalyst is added together with another ligand, preferably the same type of ligand, which can displace the original ligand coordinated to the metal of the original active polymerization catalyst, to produce in situ two different polymerization catalysts.
  • the molar ratio of the first active polymerization catalyst to the second active polymerization catalyst used will depend on the ratio of polymer from each catalyst desired, and the relative rate of polymerization of each catalyst under the process conditions. For instance, if one wanted to prepare a "toughened" thermoplastic polyethylene that contained 80% crystalline polyethylene and 20% rubbery polyethylene, and the rates of polymerization of the two catalysts were equal, then one would use a 4:1 molar ratio of the catalyst that gave crystalline polyethylene to the catalyst that gave rubbery polyethylene. More than two active polymerization catalysts may also be used if the desired product is to contain more than two different types of polymer.
  • the polymers made by the first active polymerization catalyst and the second active polymerization catalyst may be made in sequence, i.e., a polymerization with one (either first or second) of the catalysts followed by a polymerization with the other catalyst, as by using two polymerization vessels in series. However it is preferred to carry out the polymerization using the first and second active polymerization catalysts in the same vessel(s), i.e., simultaneously. This is possible because in most instances the first and second active polymerization catalysts are compatible with each other, and they produce their distinctive polymers in the other catalyst's presence. Any of the processes applicable to the individual catalysts may be used in this polymerization process with 2 or more catalysts, i.e., gas phase, liquid phase, continuous, etc.
  • the polymers produced by this process may vary in molecular weight and/or molecular weight distribution and/or melting point and/or level of crystallinity, and/or glass transition temperature and/or other factors.
  • the polymers produced are useful as molding and extrusion resins and in films as for packaging. They may have advantages such as improved melt processing, toughness and improved low temperature properties.
  • Catalyst components which include transition metal complexes of
  • such a catalyst component could include the transition metal complex supported on a support such as alumina, silica, a polymer, magnesium chloride, sodium chloride, etc., with or without other components being present. It may simply be a solution of the transition metal complex, or a slurry of the transition metal complex in a liquid, with or without a support being present.
  • Hydrogen or other chain transfer agents such as silanes (for example trimethylsilane or triethylsilane) may be used to lower the molecular weight of polyolefin produced in the polymerization process herein. It is preferred that the amount of hydrogen present be about 0.01 to about 50 mole percent of the olefin present, preferably about 1 to about 20 mole percent.
  • the relative concentrations of a gaseous olefin such as ethylene and hydrogen may be regulated by varying their partial pressures.
  • a transition metal complex of Groups 6 to 11 preferably Groups 8-1 1 , more preferably Ni or Pd, and especially preferably Ni, is used.
  • the transition metal is complexed to an "active ligand", and this ligand is bi- or higher (tri-, tetra, etc.) dentate.
  • the ligand may be neutral (have no charge) or anionic (have one or more negative charges). Bidentate ligands are preferred.
  • the active ligand has certain properties, measured by a specific test, that classify it as an active ligand.
  • the ligand may be active with one transition metal but not with another.
  • transition metal complexes when used as olefin polymerization catalyst (components), they are usually used in conjunction with other catalyst components, such as alkylating agents, and/or Lewis acids, and/or others. It has been found that these transition metal complexes, when having at least one ⁇ -allyl also coordinated to the transition metal, will initiate the polymerization of ethylene, and/or copolymerization of ethylene and ethyi-10-undecylenate, under specified conditions (see below) in the absence of any other cocatalysts. This in a sense makes them especially active in olefin polymerizations, especially polymerizations in which a polar monomer is used (and copolymerized) with a hydrocarbon olefin, especially ethylene.
  • these ligands have at least two different types of groups which coordinate to the transition metal, for example two different heteroatom groups such as (in a bidentate ligand) N and O, or N and P, or P and O, etc.
  • both the heteroatoms and the groups of which they are a part may be the same.
  • the heteroatoms may be same, but the groups of which they are a part are different, for example for nitrogen they may be amino or imino, for oxygen they may be keto or hydroxy, etc.
