| titleOfInvention | A kind of olefin polymerization catalysis and its preparation method and application |
| abstract | The present invention relates to olefin polymerization catalysis fields, disclose a kind of preparation method of olefin polymerization catalysis, comprising: (1) contact magnesium compound, organic phosphorus compound and organic epoxy compound object in a solvent, form homogeneous solution；(2) in the presence of precipitation additive, homogeneous solution is contacted to obtain mixture with titanium compound；(3) mixture is contacted with ester and alcohol, obtains solidliquid mixture；(4) optionally, solidliquid mixture is contacted with internal electron donor compound, obtains olefin polymerization catalysis, and the olefin polymerization catalysis by this method preparation and its application in olefin polymerization.By introducing ester and alcohol in the preparation process of olefin polymerization catalysis, partial size can be prepared at 25 microns or more and be spherical olefin polymerization catalysis, so as to guarantee to have preferable mobility.In addition, being not in the case where polymer bulk density reduces when the olefin polymerization catalysis is used for the polymerization reaction of alkene. |
