| Abstract: | The synthesis and characterization of metallocene complexes which can be used as catalysts in the presence of MAO for olefin polymerization were discussed in the present paper. The metallocene complexes have been characterized by IR, 1H NMR, EI-MS spectra and element analyses. The catalytic features of olefin polymerization were studied under different conditions. Metallocenes in which metals is Ti had no activity for ethylene polymerization. Polymers with different features can be obtained by using different catalysts. |
