Abstract
A metallocene complex and a preparation method therefor, a catalyst composition, an olefin polymerization method and an olefin polymer are provided. The metallocene complex has a structure of formula I. The catalyst composition containing the metallocene complex shows an improved catalytic activity, and also has relatively high structural regularity control capability for a conjugated diene structural unit and a relatively high capability for copolymerizing ethylene and conjugated diene.
