Abstract:
A method comprising contacting a silica support with a titanium-containing solution to form a titanated silica support, wherein the titanium-containing solution comprises a titanium compound, a solvent, and an amino acid. The method further comprising drying the titanated silica support to form a pre-catalyst composition; contacting a chromium-containing compound with the silica support, the titanated silica support, the pre-catalyst composition, or combinations thereof; and calcining the pre-catalyst composition to form an olefin polymerization catalyst.
