| Abstract: | Summary (C5H5)2Zr(O2C)CH3 and (C5H5)2Zr(O2C)CH2CH3 complexes were synthesized, characterized and activated with MAO for ethylene polymerization. The highest catalytic activity
was achieved at Al/Zr molar ratio of 3000 for both systems. The effects of the size of the R group in the carboxylate ligands,
the Al/Zr molar ratio and reaction temperature on the catalytic activity and polymer properties were studied and discussed. |
