    摘要: 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 compouns as shown in Formula I,

    in Formula I, R is selected from hydrogen, hydroxyl, and substituted or unsubstituted C 1 -C 30 hydrocarbyl, preferably from hydrogen, hydroxyl, and substituted or unsubstituted C 1 -C 20 alkyl, C 6 -C 30 aryl, C 6 -C 30 heteroaryl, C 7 -C 30 alkylaryl and C 7 -C 30 arylalkyl; R 1 and R 2 may be identical to or different from each other, and are selected from hydrogen and substituted or unsubstituted C 1 -C 30 hydrocarbyl, preferably from hydrogen and substituted or unsubstituted C 1 -C 20 alkyl, C 6 -C 30 aryl, C 7 -C 30 alkylaryl and C 7 -C 30 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.
