    摘要: Inorganic oxide supported chromium-containing catalysts are improved by depositing the chromium onto the inorganic oxide support in the vapor phase rather than as an inorganic or organic compound. Polymers resulting from polymerizing one or more .alpha.-olefins in the presence of such catalysts exhibit a higher molecular weight as compared to those polymers prepared in the presence of such chromium-containing catalysts prepared in the conventional manner.
