Pentalene bridged zirconocene/methylaluminoxane catalysts are described as useful for the polymerization of ethene, propene, and copolymerizations with norbornene. They show a high thermostability up to polymerization temperatures of 105 β’ C. Polyethylenes with molecular masses of 4 million g/mol ar
Metallacyclic metallocene complexes of titanium, zirconium and hafnium can be prepared by hydrogen elimination processes of suitable substituents such as -phenylalkyl or -alkenyl at the aromatic ligands. In some cases, the intermediates containing agostic hydride ligands can be isolated and characte
