The present invention refers to a process for the preparation of supported catalysts for the polymerization of olefins comprising at least a late transition metal complex, wherein the process comprises two steps. In the first step a catalytically active component comprising at least one late transition metal complex, optionally in the presence of one or more cocatalysts is mixed with a support; and in the second step the obtained mixture is treated at a reduced pressure under a flow of inert gas at a temperature equal to or below 40° C. to obtain a supported catalyst. The method is especially useful for the preparation of dual supported catalysts, useful in the gas-phase polymerization of olefins.
本发明涉及一种制备用于聚合烯烃的支持催化剂的方法,该方法包括至少一种晚期过渡
金属配合物,其中该方法包括两个步骤。在第一步中,将至少一种晚期过渡
金属配合物的催化活性组分与一种支持剂混合,可选地,在一个或多个协同催化剂的存在下。在第二步中,将得到的混合物在惰性气体流下的降压条件下,在等于或低于40°C的温度下处理,以获得支持的催化剂。该方法特别适用于制备双支持催化剂,用于气相聚合烯烃。
