In addition, a process for preparing the catalyst component and the corresponding catalyst is described. The catalyst component and its catalyst have high catalytic activity, good hydrogen response, and good stereospecificity, the catalyst can release its activity more evenly, and the obtained polymer has significantly increased bulk density.
