摘要：
The present invention relates to a new process for preparing a polypropylene using new bis(metallocene) compounds in catalyst compositions. The bis(metallocene) compounds of the invention are homo- or hetero bis(metallocene) molecules in which same or different metallocene moieties are connected by a phenylene bridge. The phenylene bridge is either para-substituted, meta-substituted or ortho-substituted by the two metallocene moieties
