Solvent activation of Mg(OEt) 2 in ethanol with carbon dioxide was carried out in a 1‐L three‐neck flask under nitrogen atmosphere, to investigate structural changes of Mg(OEt) 2 support. During activation of Mg(OEt) 2 by ethanol and CO 2 , a suspension mixture was converted to a clear solution and CO 2 was inserted into the MgO bond of Mg(OEt) 2 , to form magnesium ethyl carbonate. The solid supports were obtained from the removal of solvents by heating, during which CO 2 split off from the magnesium ethyl carbonate between 100 and 150°C. The structural changes of the obtained supports and the corresponding catalysts were checked by IR and TGA. The polymerization behavior of propylene with the catalyst and morphology of the obtained polymer were also examined. © 2001 John Wiley & Sons, Inc. J Appl Polym Sci 81: 460–467, 2001
