Preparation and Improvement of TiCI_4-Mg(OC_2H_5)_2 Catalyst for Ethylene Polymerization——Ⅱ.Formation and Composition of Carrier and Its Effect on the Performance of Catalyst |
| |
| Abstract: | The effect of preparation parameters of TiCl_4-Mg(OC_2H_5)_2 catalyst for ethylene polymerization on structure and performance of the resulting carrier was studied. The difference in structure and behaviour between β-MgCl_2 converted from Mg(OC_2H_5)_2 and α-MgCl_2 were investigated by x-ray diffraction and other techniques. The thermodecomposition during preparation of catalyst and its mechanism were also discussed. |
