| Abstract: | The formed species in preparation process of Ti-Mg system supported catalyst for olefin polymerization were determined by using IR techique. On the basis of changes of characterstic absorption peak for Si-Cl、Ti-O、C-O and C=O bond, the formed Carriers Bu—O→MgCl_2—SiCl_3 or MgCl_2 and Catalyst "Precursors" Bu—O→MgCl_2—TiCl_3 or MgCl_2·TiCl_4 were characterized. The informations of IR Spectra are in agreement with the results of polymerization reaction kinetics. |
