ABSTRACT:
Inorganic hydrogels, e.g., silica-containing hydrogels, are contacted with contacting agents comprising oxygen-containing organic compounds and then dried to remove the liquid components therefrom. The contacting agent can also be an oxygen-containing organic compound in combination with a liquid hydrocarbon or an oxygen-containing compound in combination with a liquid hydrocarbon and a surfactant. The hydrogel can be treated with a catalytic metal compound prior to or during the contacting with the contacting agents in order to produce a composition after drying and calcining that is catalytically active for olefin polymerization. The treated hydrogel can also, after drying, be treated anhydrously with a catalytic metal compound to produce a composition that is active for 1-olefin polymerization upon calcination.
