| titleOfInvention | A kind of preparation method of catalytic component for olefinic polymerization |
| abstract | The present invention provides a kind of preparation method of the catalytic component for olefinic polymerization, including elder generation with anhydrous magnesium halide is dissolved in the mixed solvent comprising oxygen-containing organic titanic compound, organic epoxy compound object, hydroxyl class compound and inert diluent and forms a kind of magnesium halide solution, and the in the mixed solvent is free of phosphate compounds；The magnesium halide solution mixes precipitation solid with halogen phosphorus-containing compound and obtains the catalytic component again；The wherein described halogen phosphorus-containing compound is such as formula O p PR 5 q X3 ‑q Compound represented, R in formula 5 It is C 1 ~C 20 Alkyl or alkoxy, 0≤q ﹤ 3, p=0 or 1, X is halogen in formula；Or the halogen phosphorus-containing compound is phosphorus pentachloride.There is catalytic component prepared by the present invention preferable particle shape, excellent hydrogen regulation performance to be conducive to use of the catalyst on slurry or gas-phase polymerization process device. |
