Abstract
Separation of methylalumoxane (MAO) by adsorption on siliceous porous materials with different average pore diameters has been carried out; polymerization of ethylene was conducted with Cp2ZrCl2 using the separated MAO as cocatalyst, it was found that the MAO adsorbed on MCM-41 with average pore size of ca. 25 Å is very effective for ethylene polymerization.Keywords
