Abstract
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 C-Chydrocarbyl, preferably from hydrogen, hydroxyl, and substituted or unsubstituted C-Calkyl, C-Caryl, C-Cheteroaryl, C-Calkylaryl and C-Carylalkyl; Rand Rmay be identical to or different from each other, and are selected from hydrogen and substituted or unsubstituted C-Chydrocarbyl, preferably from hydrogen and substituted or unsubstituted C-Calkyl, C-Caryl, C-Calkylaryl and C-Carylalkyl. 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.
