Slurry polymerization of propene using MgC1,-supported TiClJdioctylphthalate catalysts were carried out in a semibatch reactor at a constant pressure to examine the effects of polymerization conditions on catalyst activity and polymer isotacticity. The catalysts were prepared at 80, 90, and 105"C, w

Extended X-ray absorption fine structure analysis (EXAFS) has been used to study supported TiCl,/MgCI, catalysts containing 1.8 wt.-% Ti. Adsorbed TiCI, was found to exist on the MgC12 surface as a dimeric complex. The possible structures of dimeric TiC14 complexes on the (100) face of MgCl, are dis
Ethene was copolymerized in liquid propene with a high activity heterogeneous MgCI2/TiCI 4triethytaluminium catalyst and with homogeneous VOCl3-diethylaluminiumchloride and Cp2ZrCl2-methylaluminoxane catalysts to study the effect of the catalyst system on the properties of the products. The titanium
