Catalyst component for propene polymerization, preparation method thereof, and catalyst containing the same
The present invention discloses a catalyst component for propene polymerization, comprising titanium, magnesium, halogen, and internal electron donor A, wherein said internal electron donor A is selected from the compounds as shown in Formula I, in Formula I, R is selected from hydrogen, hydroxyl, and substituted or unsubstituted C1-C30 hydrocarbyl, preferably from hydrogen, hydroxyl, and substituted or unsubstituted C1-C20 alkyl, C6-C30 aryl, C6-C30 heteroaryl, C7-C30 alkylaryl and C7-C30 arylalkyl; R1 and R2 may be identical to or different from each other, and are selected from hydrogen and substituted or unsubstituted C1-C30 hydrocarbyl, preferably from hydrogen and substituted or unsubstituted C1-C20 alkyl, C6-C30 aryl, C7-C30 alkylaryl and C7-C30 arylalkyl. According to the present invention, by using the compound as shown in Formula I as internal electron donor compound for propene polymerization, the catalyst has a higher activity, and a slow rate of delay of activity. The obtained polymer has not only a wider molecular weight distribution, but also a high melt index and isotacticity.
