AbstractTetramethyldisilane-bridged bis(l-indenyl and tetrahydroindenyl) metallocene dichlorides (Me2SiSiMe2) Ind(2)MCl(2) [M = Ti (1), Zr (2)] and (Me2SiSiMe2) [IndH(4)](2)MCl2[M = Ti (3), Zr(4)] were -synthesized, Complexes 1-4 were characterized by H-1 NMR, mass spectra and elemental analyses, Complexes 3 and 4 were used for the polymerization of ethylene after activation with methyl aluminoxane(MAO) at different temperatures and normal pressure, The titanocene 3 shows a lower activity but produces polyethylene with a higher molecular weight than zirconocene 4, The catalyst systems show a dependency of the activity and molecular weight on temperature.
