Реферат: It was found by chromatography and 13C NMR spectroscopy that diethyl 2,3-diisobutyl succinate (DIBS), which is used as a stereoregulating electron donor in titanium–magnesium catalysts, exists as a mixture of rac and meso stereoisomers. Their molecular structure was calculated using the DFT method. It was ascertained that mainly rac-DIBS is anchored to the surface of MgCl2. Subsequent interaction between the MgCl2/DIBS sample and TiCl4 leads to further removal of meso-DIBS. Titanium–magnesium catalysts of composition MgCl2/DIBS/TiCl4 prepared by different procedures contain 85–91% rac-DIBS. The IR spectroscopy data on the stereoisomeric configuration of DIBS in MgCl2/DIBS samples and titanium–magnesium catalysts MgCl2/DIBS/TiCl4 prepared by different procedures and the data on propylene polymerization over these catalysts are presented.
