摘要: A process for producing substantially amorphous propylene (co)polymers, comprising contacting propylene optionally in the presence of one or more olefins under polymerization conditions with a catalyst system comprising: A) a half sandwich titanium complex wherein the cyclopentadienyl is substituted with one or two heterocyclic rings, according to formula (I): cf formula (I) in claim 1: wherein X is N or P; Z is C, Si or Ge; Y1 is an atom selected from the group consisting of NR7, O, PR7 or S; Y2 is selected from the group consisting of CR8 or Y1 and m is 0 or 1 and B) an activating cocatalyst. The above titanium complex and the ligand useful as intermediates in their synthesis are also described.
