✦ Synopsis

A supported titanium catalyst was prepared using magnesium ethoxide as a precursor for the support. The catalyst was characterized by compositional analysis and specific surface area measurements. The propylene polymerization studies were carried out with a solid titanium catalyst [Mg, Ti] using tetraisobutylaluminoxane as cocatalyst. The results have been compared with a triisobutylaluminum based system. Both systems show a decay type kinetic profile. The [Mg, Ti]-tetraisobutylaluminoxane catalyst system shows high activity and high stereospecificity as compared to the [Mg, Ti]-triisobutyl aluminum.
