ABSTRACT:
A metallocene having an asymmetric ligand which is represented by the formula below and its enantiomer: ##STR1## and a process for producing a polyolefin using the same as a catalyst component. The metallocene and its enantiomer are particularly effective in the production of highly stereospecific polyolefins.
