Definitions
- This invention relates to metathesis preparation of triblock polymers from vinyl- terminated polyolefins.
- Metathesis is generally thought of as the interchange of radicals between two compounds during a chemical reaction. There are several varieties of metathesis reactions, such as ring opening metathesis, acyclic diene metathesis, ring closing metathesis and cross metathesis.
- Methods for the production of polyolefins with end-functionalized groups are typically multi-step processes that often create unwanted by-products and waste of reactants and energy.
- metathesis reactions can provide functionalized polyolefins that have end-functionalization.
- polymerize polyolefins having end-functionalization to each other it has not been feasible to polymerize polyolefins having end-functionalization to each other.
- Triblock polymers prepared by metathesis from multiblocks of vinyl-terminated polyolefins feature a chemically reactive internal site of unsaturation and are of interest for use in a broad range of applications as compatibilizers, tie-layer modifiers, surfactants, and surface modifiers. Hydrogenation leads to unique triblock polymers that can be used in applications such as those noted for the unhydrogenated materials.
- a novel method for their production by the metathesis of multiblocks of vinyl-terminated polyolefins is useful in a range of polyolefins, including isotactic polypropylene (iPP), atactic polypropylene (aPP), ethylene propylene copolymer (EP), and polyethylene (PE).

Drying of the support material can be effected by heating or calcining at about 100°C to about 1000°C, preferably at least about 600° C. When the support material is silica, it is heated to at least 200°C, preferably about 200°C to about 850°C, and most preferably at about 600°C; and for a time of about 1 minute to about 100 hours, from about 12 hours to about 72 hours, or from about 24 hours to about 60 hours.
- the calcined support material must have at least some reactive hydroxyl (OH) groups to produce the catalyst system of this invention.
- the calcined support material is then contacted with at least one polymerization catalyst comprising at least one metallocene compound and an activator.
- the support material having reactive surface groups, typically hydroxyl groups, is slurried in a non-polar solvent and the resulting slurry is contacted with a solution of a metallocene compound and an activator.
- the slurry of the support material in the solvent is prepared by introducing the support material into the solvent, and heating the mixture to about 0 to about 70°C, preferably to about 25 to about 60°C, preferably at room temperature. Contact times typically range from about 0.5 hours to about 24 hours, from about 0.5 hours to about 8 hours, or from about 0.5 hours to about 4 hours.
- Suitable non-polar solvents are materials in which all of the reactants used herein, i.e., the activator, and the metallocene compound, are at least partially soluble and which are liquid at reaction temperatures.
- Preferred non-polar solvents are alkanes, such as isopentane, hexane, n-heptane, octane, nonane, and decane, although a variety of other materials including cycloalkanes, such as cyclohexane, aromatics, such as benzene, toluene and ethylbenzene, may also be employed.
- the support material is contacted with a solution of a metallocene compound and an activator, such that the reactive groups on the support material are titrated, to form a supported polymerization catalyst.
- the period of time for contact between the metallocene compound, the activator, and the support material is as long as is necessary to titrate the reactive groups on the support material.
- titrate is meant to react with available reactive groups on the surface of the support material, thereby reducing the surface hydroxyl groups by at least 80%, at least 90%, at least 95%, or at least 98%.
- the surface reactive group concentration may be determined based on the calcining temperature and the type of support material used.
- the support material calcining temperature affects the number of surface reactive groups on the support material available to react with the metallocene compound and an activator: the higher the drying temperature, the lower the number of sites.
- the support material is silica which, prior to the use thereof in the first catalyst system synthesis step, is dehydrated by fluidizing it with nitrogen and heating at about 600°C for about 16 hours, a surface hydroxyl group concentration of about 0.7 millimoles per gram (mmols/gm) is typically achieved.
- mmols/gm millimoles per gram
- the exact molar ratio of the activator to the surface reactive groups on the carrier will vary. Preferably, this is determined on a case-by-case basis to assure that only so much of the activator is added to the solution as will be deposited onto the support material without leaving excess of the activator in the solution.
- the amount of the activator which will be deposited onto the support material without leaving excess in the solution can be determined in any conventional manner, e.g., by adding the activator to the slurry of the carrier in the solvent, while stirring the slurry, until the activator is detected as a solution in the solvent by any technique known in the art, such as by !fi NMR.
- the amount of the activator added to the slurry is such that the molar ratio of B to the hydroxyl groups (OH) on the silica is about 0.5: 1 to about 4: 1, preferably about 0.8: 1 to about 3 : 1, more preferably about 0.9: 1 to about 2: 1 and most preferably about 1 : 1.
- the amount of boron on the silica may be determined by using ICPES (Inductively Coupled Plasma Emission Spectrometry), which is described in J. W. Olesik, "Inductively Coupled Plasma- Optical Emission Spectroscopy," in the Encyclopedia of Materials Characterization, C. R. Brundle, C. A. Evans, Jr. and S.
