    Abstract: A gas phase polymerization process comprising: (1) preparing a solution of a catalyst precursor comprising a mixture of magnesium and titanium compounds, an electron donor and a solvent; (2) adding a filler to the solution from step (1) to form a slurry; (3) spray drying the slurry from step (2) at a temperature of 100 to 140 °C to form a spray dried precursor; (4) slurring the spray dried precursor from step (3) in mineral oil, (5) partially or fully pre-activating the catalyst precursor by contacting the slurry of (4) with one or more Lewis Acids, and (6) transferring the partially or fully activated precursor from step (5) into a gas phase reactor in which an olefin polymerization reaction is in progress.

    Abstract translation: 一种气相聚合方法，包括：（1）制备包含镁和钛化合物，电子给体和溶剂的混合物的催化剂前体溶液; （2）向步骤（1）的溶液中加入填料以形成浆料; （3）在100〜140℃的温度下喷雾干燥步骤（2）的浆料，形成喷雾干燥的前体; （4）将来自步骤（3）的喷雾干燥的前体在矿物油中捣碎，（5）通过使（4）的浆料与一种或多种路易斯酸接触来部分或全部预活化催化剂前体，和（6）将 部分或完全活化的步骤（5）的前体进入进行烯烃聚合反应的气相反应器。
