摘要:New bisindenyl ligand complexes and catalysts comprising those complexes. The invention is directed to improving the manufacturing of specific C1-symmetric bisindenyl complexes by modifying one of the indenyl ligands in order to improve the selectivity of the complex synthesis towards the desired anti-isomer, increase the yield and simplify the purification of the complex. The invention also relates to the use of the new bisindenyl metallocene catalysts for the production of polypropylene homopolymers or propylene copolymers.
