    摘要: A process for the preparation of a catalyst material and the resultant catalyst material. The process comprises the steps of: (a) treating a particulate support material with an alkylating agent; (b) contacting the alkylating agent treated support material with a procatalyst; optionally (c) contacting the support material with an ionic catalyst activator, and optionally (d) recovering the catalyst-carrying support material. The process allows the simple and effective alkylation of procatalysts, such as metallocene procatalysts. The procatalyst comprises at least one triaza containing ligand.
