Synthesis and Morphologycal Investigation on Ziegler-Natta Spherical Catalyst

polyolefins are the main product of polymerization industry. Since catalyst has the most important role in polymerization industry and on the other hand, morphology and properties of produced polymers are highly dependent on the catalyst properties and morphology. In this paper the effect of stirrer speed, Alcohol/MgCl2 molar ratio and adduct injection time to the second reactor on the spherical catalyst support were investigated. Result show with increasing the injection time, Particle size average (PSA) of catalyst increased. On the other hand, with increasing in the stirrer speed, PSA decreased. Increasing the alcohol content results in decreasing the PSA of catalyst.
