Two Ti complexes with bidentate ligands derived from pinacol and perfluoropinacol and activated with a binary Al(C 2 H 5 ) 2 Cl ‐ Mg(C 4 H 9 ) 2 cocatalyst are efficient catalysts for polymerization of lightest alkenes, ethylene and propylene, and for their copolymerization. They produce linear polyethylene of moderate molecular weight and essentially atactic amorphous polypropylene. Ethylene/propylene copolymers prepared with these catalysts are compositionally uniform resins with a very low crystallinity degree which can be used as synthetic EPM rubbers.
