摘要： The present invention relates to new bis(metallocene) compounds, new catalyst compositions, process for preparing the new bis(metallocene) compounds and use of said new catalyst compositions to polymerise olefins. 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.
