Abstract

The invention provides catalyst components for an olefin polymerization reaction, and a catalyst thereof. The catalyst components comprise magnesium, titanium, halogen and electron donor, wherein the electron donor comprises at least one selected from diol ester compounds. When the diol ester compound comprises a certain amount of an isomer having a fischer projection represented by (II), activity and stereospecificity of the catalyst are improved substantially, in particular, when a polymer with the high fusion index is produced, a isotactic index of the produced polymer is raised substantially.

Description

technical field

[0001] The present invention relates to a solid catalyst component containing a glycol ester compound of special structure and its preparation method, as well as the catalyst containing the solid catalyst component and the application of the catalyst in olefin polymerization, especially in propylene polymerization The application of high yield, high isotactic and wide molecular weight distribution polymer can be obtained. technical background

[0002] It is well known that solid titanium catalyst components based on magnesium, titanium, halogen and electron donors can be used in olefin polymerization, especially in the polymerization of α-olefins with 3 or more carbon atoms. Polymers with higher yield and higher stereoregularity, in which the electron donor compound is one of the essential components in the catalyst component, and with the development of the internal electron donor compound, the polyolefin catalyst is constantly updated, Currently, a large n...
