Catalyst component for olefin polymerization, and catalyst containing the same

A catalyst component for olefin polymerization, comprising magnesium, titanium, halogen and an internal electron donor, wherein said internal electron donor comprises an imine compound as shown in Formula I,

• wherein n is an integer ranging from 0 to 10;
• A is carbon or a heteroatom selected from the group consisting of oxygen, sulfur, nitrogen, boron, and silicon;
• R and R′ may be identical to or different from each other, each independently selected from hydroxyl, halogen atom substituted or unsubstituted C1-C20 alkyl, C2-C20 alkenyl, C6-C20 alkaryl, C10-C20 fused aryl, phenyl, halogenated phenyl, alkyl phenyl, or terphenyl;
• R1 and R2 may be identical to or different from each other, each independently selected from halogen atom substituted or unsubstituted C1-C20 alkyl, C3-C20 cycloalkyl, C2-C20 alkenyl, C2-C20 ester group, C6-C20 aryl, or C10-C20 fused aryl;
• each of RI, RII, R3 and R4 may be independently selected from hydrogen, halogen atom substituted or unsubstituted C1-C20 alkyl, C3-C20 cycloalkyl, C2-C20 alkenyl, C2-C20 ester group, C6-C20 aryl, or C10-C20 fused aryl, and one or more of R1-R4, and RI and RII may be bonded together to form a ring;
• R3-R4, and RI and RII may optionally contain one or more heteroatoms as a substitute of a carbon or hydrogen atom or both, the heteroatom being oxygen, sulfur, nitrogen, boron, silicon, phosphorus, or halogen atom,
• with the provisos that when A is oxygen, or sulfur, RI and RII are absent;
• when A is nitrogen or boron, one of RI and RII is absent;
• and when n is zero, R3 and R4 are independently selected from halogen atom substituted C1-C20 alkyl, halogen atom substituted C3-C20 cycloalkyl, halogen atom substituted C2-C20 alkenyl, halogen atom substituted or unsubstituted C2-C20 ester group, halogen atom substituted C6-C20 aryl, or halogen atom substituted C10-C20 fused aryl.
