A ligand for a metallocene catalyst used to prepare propylene based polymers, and its preparation method

Abstract

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 cyclopcntadicnyl is substituted with one or two heterocyclic rings; and(B) an activating cocatalyst. The above titanium complex and the ligand useful as intermediates in their synthesis are also described
