    • This invention relates to a process to produce a supported metallocene catalyst system, the process comprising: (i) contacting a support material with an alkyl aluminum compound to provide an alkyl aluminum treated support material; wherein the alkyl aluminum compound is represented by the formula: R3Al; wherein each R group is, independently, a substituted or unsubstituted C1 to C12 alkyl group, Cl or F with the proviso that at least one R group is a C1 to C12 alkyl group; (ii) contacting the alkyl aluminum treated support material with an ionic stoichiometric activator, wherein the ionic stoichiometric activator is represented by the formula: (Z)d+Ad−; wherein (Z)d+ is a cation, where Z is a reducible Lewis Acid, Ad− is a non-coordinating anion having the charge d−, and d is 1, 2, or 3; (iii) contacting a metallocene compound comprising a group 4, 5, or 6 metal with the alkyl aluminum treated support material; and (iv) obtaining a supported metallocene catalyst system.
    • 本发明涉及一种生产负载型金属茂催化剂体系的方法,该方法包括:(i)使支撑材料与烷基铝化合物接触以提供烷基铝处理的载体材料; 其中所述烷基铝化合物由下式表示:R3Al; 其中每个R基团独立地为取代或未取代的C1至C12烷基,C1或F,条件是至少一个R基团为C1至C12烷基; (ii)使烷基铝处理的载体材料与离子化学计量活化剂接触,其中离子化学计量活化剂由下式表示:(Z)d + Ad-; 其中(Z)d +是阳离子,其中Z是可还原路易斯酸,Ad-是具有电荷d-的非配位阴离子,d是1,2或3; (iii)使包含第4,5或6族金属的茂金属化合物与烷基铝处理的载体材料接触; 和(iv)获得负载型茂金属催化剂体系。
