A process for the polymerization of olefins, in particular a process for the copolymerization of propylene with further olefins, is carried out in the presence of highly active catalyst systems comprising specifically selected metallocenes, in particular ones which bear different substituents in position 2 and position 4 on an indenyl ligand. Novel polypropylene copolymers can be obtained by this process.

Ligand systems containing indenyl structures, transition metal compounds of the metallocene type and catalyst systems comprising such transition metal compounds are described. The novel transition metal compounds can be used in the polymerization of olefins, in particular to give polyolefins having a low molar mass.
