| titleOfInvention | The preparation method of the poly- MAO composition of small particle size solid shape |
| abstract | The present invention provides the preparation method of a kind of solid polymethylaluminoxancomposition composition and preparation method thereof, polymerization catalyst and olefin polymer, the solid polymethylaluminoxancomposition composition does not utilize silica etc., for the particulate less than 5 μm, also evenly, the polymerization activity when preparing olefin polymer is also high for particle diameter.The preparation method of the solid polymethylaluminoxancomposition composition of the present invention is related to a kind of solid polymethylaluminoxancomposition composition, the aluminium content of the composition is in the range of the mass % of 36 mass % ~ 43, it is 12 moles of below % from the molar fraction of the methyl at trimethyl aluminium position, and for particle shape, median diameter on the basis of volume for 0.1 μm ~ be less than 5 μm of scope.The process of solid polymethylaluminoxancomposition composition is separated out the aromatic species hydrocarbon solution containing poly- MAO and trimethyl aluminium is heated, and includes bubble drying inert gas before heating or when heating. |
