    摘要： The subject invention provides a process for preparing an olefin polymerization catalyst wherein a calcined and passivated silica support (support precursor) is sequentially contacted with a first solution of a metal complex or of a cocatalyst, and thereafter with a second solution of the other of the metal complex or the cocatalyst, wherein the second solution is provided in an amount such that 100 percent of the pore volume of the support precursor is not exceeded. Optionally, the compatible solvent of the first and/or second solutions is removed. The subject invention further provides a process for polymerizing one or more α-olefins in the presence of the olefin polymerization catalyst prepared by the process of the invention.
