| titleOfInvention | Solid catalyst component for olefin polymerization, catalyst and application thereof |
| abstract | The invention provides a solid catalyst component for olefin polymerization, which comprises Mg, Ti, halogen and at least two electron donors, wherein one electron donor is a 2-substituted amino-phenyl ester compound A selected from a general formula (I), and the other electron donor is a Lewis base compound B containing one or more electronegative groups. The invention also discloses a catalyst containing the solid catalyst component and application of the catalyst in olefin polymerization reaction, in particular application in propylene polymerization reaction. The catalyst has high activity, can obtain polypropylene with high isotacticity and wide molecular weight distribution, can also obtain polypropylene with high isotacticity without an external electron donor, reduces Al/Ti and Al/Si during polymerization, prolongs the polymerization time, can still maintain high activity, and is suitable for producing low-ash polymers. |
