| titleOfInvention | A supported non-metallocene catalyst and its preparation method and application |
| abstract | The invention relates to a magnesium carrier supported non-metallocene catalyst, a preparation method and application thereof. The preparation method of the magnesium carrier-supported non-metallocene catalyst includes the following steps: dissolving the magnesium compound and the non-metallocene ligand in alcohol, adding a diluting solvent, mixing, and drying to obtain a magnesium carrier, wherein the alcohol in the magnesium carrier is an alcohol. The content of the aluminum alloy is 1.0-3.0wt% relative to the weight ratio of the magnesium carrier, preferably 1.1-2.5wt%, more preferably 1.5-2.0wt%; the alkyl aluminum is added to the magnesium carrier for reaction, and the step of obtaining the magnesium-aluminum carrier after filtering ; at -40～10°C, preferably at -20～0°C, the magnesium-aluminum carrier is treated with a chemical treatment agent selected from IVB group metal compounds to obtain the magnesium carrier-supported non-metallocene catalyst step. The supported non-metallocene catalyst has the characteristics of simple and easy preparation method, flexible and adjustable polymerization activity and the like. |
