Definitions
- the present invention relates to supported catalysts suitable for the polymerisation of olefins and in particular to supported catalysts suitable for the preparation of polymers having broad molecular weight distributions and improved melt strengths.
- Metallocene catalysts offer the advantage of generally higher activity than traditional Ziegler catalysts and are usually described as catalysts which are single-site in nature. Because of their single-site nature the polyolefm copolymers produced by metallocene catalysts often are quite uniform in their molecular structure.
- MWD molecular weight distributions
- SCBD narrow Short Chain Branching Distribution
- the metallocene complex comprises a bis(cyclopentadienyl) zirconium complex for example bis(cyclopentadienyl) zirconium dichloride or bis(tetramethylcyclopentadienyl) zirconium dichloride.
- Examples of such complexes maybe found in EP 129368, EP 206794, and EP 260130.
- the metal complex is used in the presence of a suitable activator.
- the activators most suitably used with such metallocene complexes are aluminoxanes, most suitably methyl aluminoxane (MAO).
- Other suitable activators are boron compounds, in particular perfmorinated boron compounds.
- complexes having a single or mono cyclopentadienyl ring have been developed. Such complexes have been referred to as 'constrained geometry' complexes and examples of these complexes may be found in EP 416815 or EP 420436. In such complexes the metal atom eg. zirconium or titanium is in the highest oxidation state.
- activators are aluminoxanes, in particular methyl aluminoxane or compounds based on boron compounds.
- boranes for example tris(pentafluorophenyl) borane, or borates such as trialkyl-substituted ammonium tetraphenyl- or tetrafluorophenyl-borates.
- Catalyst systems incorporating such borate activators are described in EP 561479, EP 418044 and EP 551277.
- metallocene complexes When used for the gas phase polymerisation of olefins, metallocene complexes may typically be supported for example on an inorganic oxide such as silica. Such supports may be typically dehydrated by calcining before use or may be pretreated with an organoaluminium compound to passivate the surface of the silica.
- complexes are amidosilane - or amidoalkanediyl complexes. Most preferred complexes are those wherein M is titanium. Specific complexes suitable for use in the preparation of the supported catalysts of the present invention are those disclosed in WO 95/00526 and are incorporated herein by reference.
- aluminoxanes suitable for use in the present invention may be commercially available materials or may be such commercially available material that has been dried under vacuum prior to its use for the preparation of the supported catalyst compositions.
- Preferred organoboron compounds are triarylboron compounds, in particular perfluorinated triarylboron compounds.
- a particularly preferred activator component comprises an organoboron compound and an organoaluminium compound.
- a supported catalyst system comprising (a) a dehydrated support material
- the preferred ionic compounds used as activators are those wherein the cation of the ionic compound comprises a hydrocarbyl substituted ammonium salt and the anion comprises an aryl substituted borate.
- Typical borates suitable as ionic compounds include: triethylammonium tetraphenylborate triethylammonium tetraphenylborate, tripropylammonium tetraphenylborate, tri(n-butyl)ammonium tetraphenylborate, tri(t-butyl)ammonium tetraphenylborate, N,N-dimethyl anilinium tetraphenylborate, N,N-diethylanilinium tetraphenylborate, trimethylammonium tetrakis(pentafluorophenyl) borate, triethylammonium tetrakis(pentafluorophenyl) borate, tripropylammonium tetrakis(pentafluorophenyl) borate, tri(n-butyl) ammonium tetrakis(pentafluoropheny
- a preferred type of activator suitable for use with the metallocene complexes of the present invention comprise ionic compounds comprising a cation and an anion wherein the anion has at least one substituent comprising a moiety having an active hydrogen.
- Particular preferred activators of this type are alkylammonium tris(pentafluorophenyl) 4-(hydroxyphenyl) borates.
- a particularly preferred activator is , bis(hydrogenated tallow alkyl) methyl ammonium tris (pentafiuorophenyl) (4- hydroxyphenyl) borate.
- the supported catalyst systems of the present invention are most suitable for operation in processes which typically employ supported polymerisation catalysts.
- the supported catalysts of the present invention may be suitable for the polymerisation of olefin monomers selected from (a) ethylene, (b) propylene (c) mixtures of ethylene and propylene and (d) mixtures of (a), (b) or (c) with one or more other alpha-olefms.
- Particularly preferred polymerisation processes are those comprising the polymerisation of ethylene or the copolymerisation of ethylene and ⁇ -olefins having from 3 to 10 carbon atoms.
- the supported catalyst systems described herein may be used to prepare copolymers having a broad molecular weight distribution as well as improved melt strengths.
- the copolymers also exhibit melt strength values (16 Mpa) in the range 3 - 12 cN and preferably in the range 3 - 9 cN.
- copolymers are preferably prepared by use of a supported metallocene catalyst system as hereinbefore described.
- the preferred supported catalyst system for this aspect of the present invention is that wherein the transition metal compound is a monocyclopentadienyl metallocene complex as hereinbefore described.
- the preferred process for the preparation of such copolymers is a gas phase process.
- the present invention also encompasses a dehydrated catalyst support material characterised in that the support. material has been treated with at least two different organoaluminium compounds prior to the addition of further catalytic components.
- a 2.5 1 double jacketed thermostatic stainless steel autoclave was purged with nitrogen at 70°C for at least one hour. PE pellets previously dried under vacuum at 80°C for 12 hours were introduced and the reactor was then purged three times with nitrogen (7 bar to atmospheric pressure). -0.13 g of TEA treated silica (1.5 mmol TEA/g) was added under pressure and allowed to scavenge impurities for at least 15 minutes under agitation. The gas phase was then composed (addition of ethylene, 1-hexene and hydrogen) and a mixture of supported catalyst (-0.1 g) and silica/TEA (-0.1 g) was injected.
- a constant pressure of ethylene and a constant pressure ratio of ethyl ene/co- monomer were maintained during the run.
- the run was terminated by venting the reactor and then purging the reactor 3 times with nitrogen.
- the PE powder produced during the run was then separated from the PE seed bed by simple sieving.
- polymer produced separated from polymer bed by simple sieving was obtained having the following properties:
- SiO2/TEA impregnated used as scavenger SiO2/TEA impregnated used as scavenger.
- the melt strength of the polymer is measured at 190°C, using a Gottfert Rheotens extensional rheometer in conjunction with a Rosand RH 7 Capillary Rheometer. This is achieved by extruding the polymer at a constant pressure (P) through a die of 1.5 mm diameter and 30 mm in length, with a 90° entry angle. Once a given extrusion pressure is selected, the piston of the capillary rheometer will travel through its 15 mm diameter barrel at a speed that is sufficient to maintain that pressure constant. The nominal wall shear rate ( / ) for a given extrusion pressure can then be computed for the polymer at the selected pressure using the constant pressure ratio system of the rheometer.
- the extrudate is drawn with a pair of gear wheels at an accelerating speed (V).
- the acceleration ranges from 0.12 to 1.2 cm s ⁇ depending on the flow properties of the polymer under test.
- the drawing force (F) experienced by the extrudate is measured with a transducer and recorded on a chart recorder together with the drawing speed.
- the maximum force at break is defined as melt strength (MS) at a constant extrusion pressure (P) or at its corresponding extrusion rate ( ⁇ ).
- MS melt strength
- P constant extrusion pressure
- ⁇ extrusion rate
- Three or four extrusion pressures (6, 8, 12, 16 MPa) are typically selected for each polymer depending on its flow properties. For each extrusion pressure, a minimum of 3 MS measurements is performed and an average MS value is then obtained.
- the derivative function of the extrusion pressure dependent melt strength, ⁇ (MS)/ ⁇ (P) for each polymer is computed from the slope (by a least square line fitting) of the plot of the average MS against pressure.
- the mean melt strength at an extrusion pressure of 16 MPa, MS (16 MPa), can be computed from the plot.
