    摘要： A catalyst component for olefin polymerization which contains magnesium, titanium, halogen and electron donors is provided in the present invention. The electron donors are selected from at least one succinate compounds of following general formula (I), and the content of said succinate compounds with the structure as shown in Formula (II) in said succinate compounds (I) is less than 100%, but not less than 51.0 wt %. Compared with the mesomer whose content with the structure as shown in Formula (II) is 100%, the catalyst component provided by the present invention not only greatly decreases the manufacturing cost, but also improves certain properties of the catalyst, for example the molecular weight distribution of polymer obtained by catalytic reaction using said catalyst is wider, which is beneficial for improving processing properties of polymers. The corresponding catalyst is also provided.
