## Abstract The MgCl~2~ support for a propene polymerization catalyst was prepared by the recrystallization method using ethanol as a solvent and ethyl benzoate as an internal electron donor. The recrystallized MgCl~2~ was impregnated with TiCl~4~ at various temperatures, and the effect of impregna
This study focuses on the kinetics of ethylene/propylene (homo/co)polymerization reactions using a high activity TiCl 4 /MgCl 2 /AlEt 3 catalyst. The reactor system is a gas phase reactor equipped with an on-line composition control scheme. As such, important kinetic data such as the instantaneous r
## Abstract The stereosequence distribution in the heptaneโinsoluble fraction of polypropene samples prepared with a number of MgCl~2~โsupported catalysts was analyzed in detail by means of ^13^CNMR. The results indicate that what is conventionally taken as โisotacticโ polypropene is normally a ste
## Abstract ^13^C NMR analysis of relatively lowโmolecularโweight polypropylenes prepared using the catalyst system MgCl~2~/TiCl~4~/phthalate esterโAlEt~3~โexternal Lewis base has revealed the presence of up to around 20% butyl (__n__โBu) chain ends, indicative of regioirregular (2,1โ) monomer inse
