A polymerization process. In some embodiments, a polymerization process can include introducing a carrier fluid, an olefin, and a catalyst feed into a polymerization reactor, where the catalyst feed comprises one or more catalysts, a carrier liquid, and optionally an induced condensing agent. In some embodiments, the combined amount of carrier liquid and any induced condensing agent in the catalyst feed is > = 350 kg/mole of the one or more catalysts introduced into the polymerization reactor. The method may also include polymerizing the olefin in the polymerization reactor in the presence of the catalyst to produce a polymer product. 聚合方法。在一些实施例中，聚合方法可以包括将载体流体、烯烃和催化剂进料引入聚合反应器中，其中催化剂进料包含一种或多种催化剂、载体液体和任选的诱导冷凝剂。在一些实施例中，催化剂进料中载体液体和任何诱导冷凝剂的合并量是≥350kg/摩尔引入聚合反应器中的该一种或多种催化剂。该方法还可以包括使烯烃在催化剂的存在下在聚合反应器内聚合以产生聚合物产物。
