A process for polymerizing propylene is disclosed. The propylene is polymerized with a catalyst system which comprises an activator and a [1,2- b]indenoindolyl Group 4-6 transition metal complex having open architecture. The process has high catalyst activity and gives high molecular weight elastomeric polypropylene.
L'invention concerne un procédé de polymérisation de propylène. Le propylène est polymérisé au moyen d'un système catalyseur comprenant un activateur et un complexe de métal de transition du groupe 4-6 [1,2-b]indénoindolyl, présentant une architecture ouverte. Ce procédé présente une activité hautement catalytique et permet d'obtenir du polypropylène élastomère de poids moléculaire élevé.
