Abstract
Separation of methylalumoxane (MAO) by adsorption on siliceous porous mater ials with different average pore diameters has been carried out; polymeriza tion of ethylene was conducted with Cp2ZrCl2 using the separated MAO as coc atalyst, it was found that the MAO adsorbed on MCM-41 with average pore siz e of ca. 25 Angstrom is very effective for ethylene polymerization.
