Title:
SOLID CATALYST COMPONENT FOR USE IN OLEFIN POLYMERISATION, CATALYST, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/161854
Kind Code:
A1
Abstract:
Provided in the present invention is a solid catalyst component for use in olefin polymerisation, comprising Mg, Ti, a halogen, and at least one electron donor, the electron donor being a 2-substituted amino-phenyl ester compound selected from general formula (I). Also disclosed in the present invention are a catalyst comprising the solid catalyst component, and an application for the catalyst in olefin polymerisation, particularly in propylene polymerisation. Also provided in the present invention is a high activity catalyst, said catalyst being able to obtain polypropylene of high isotacticity and wide molecular weight distribution, and not requiring an external electron donor to obtain high isotacticity polypropylene; during polymerisation, Al/Ti and Al/Si are reduced, the polarisation time is lengthened, and high activity can still be maintained, suitable for producing low-ash polymers.
