A series of symmetric and nonsymmetric tetrahydroindenyl zirconium complexes was obtained by the reaction of ZrCl4 or (CpTMS)ZrCl3 with lithium salts of the corresponding tetrahydroindenes. Activated with methylalumoxane, these complexes exhibit high activity in polymerization of ethylene (up to 6.8∙106 g PE (mol Zr h)–1), as well as in copolymerization of ethylene and hex-1-ene (up to 8.6∙106 g PE...
