| titleOfInvention | A kind of propene polymer and its preparation method and application |
| abstract | The invention provides a kind of propene polymer and its preparation method and application, the method is included in gas-phase polymerization reactor, under alkene gas-phase polymerization condition, by propylene, ethene be selected from Cn 4 -Cn 8 alpha-olefin contact with olefin polymerization catalyst system, described olefin polymerization catalyst system contains solid ingredient, external donor compound and organo-aluminium compound, described solid ingredient contains carrier and load titanium compound on the carrier and internal electron donor compound, the granularity of described solid ingredient is within the scope of 8-150 micron, and the size distribution curve of described solid ingredient is unimodal distribution.Method of the present invention can suppress the inter-adhesive caking of polymer beads in gas-phase polymerization processes effectively, guarantees the smooth and easy of production process; The composition of propene polymer of the present invention evenly and stable performance, is particularly useful for making polymeric film. |
