| titleOfInvention | Solid PMAO composition and method for producing the same |
| abstract | The present invention is a method for producing a solid PMAO composition comprising steps (a) to (c). Step (a): The aromatic hydrocarbon solution of PMAO and TMAL containing the unit of the general formula (I) is heated to precipitate a solid PMAO composition containing PMAO and TMAL. More than 70% of the aluminum conversion of PMAO and TMAL precipitates. Step (b): To the obtained solution containing the solid PMAO composition, an aromatic hydrocarbon solution containing PMAO and TMAL of the unit represented by the general formula (I) is added. Step (c): The obtained solution is heated to precipitate a solid PMAO composition. More than 70% of the aluminum conversion of PMAO and TMAL precipitates. The median diameter d2 of the solid PMAO composition generated in the step (c) is greater than the median diameter d1 of the solid PMAO composition generated in the step (a), and the heating temperature in the step (c) is the same as that in the step (a). The heating temperature is the same or different. (In the formula, n represents an integer of 10 to 50.) According to the present invention, a highly active solid PMAO composition can be obtained even under severe conditions with large particle size and close to the actual reaction process. Provided are a catalyst for olefin-based polymerization using the solid PMAO composition, and a method for producing an olefin-based polymer using the catalyst. ‑[(Me)AlO] n ‑(I). |
