    • The purpose of the invention is to provide a process for producing a prepolymerization catalyst component which is homogeneous and does not a tendency that it adheres to a wall surface of a dryer and that the prepolymerization catalyst component are aggregated with each other. The process comprises the following steps (1) to (4):step (1): heat-treating a solution containing a metallocene-based compound (B1), which is prepared by dissolving the metallocene-based compound (B1) shown below in a saturated hydrocarbon solvent, at 40° C. or above to obtain a heat-treated material (1); step (2): heat-treating a mixture of the heat-treated material (1) and a metallocene-based compound (B2) shown below at 40° C. or above to obtain a heat-treated material (2); step (3): subjecting the above heat-treated material (2) and a cocatalyst support (A) to a contact treatment to obtain a contact treatment product (3); and step (4): subjecting the contact treatment product (3) and an organoaluminum compound (C) to a contact treatment to obtain a contact treatment product (4).
    • 本发明的目的是提供一种制备预聚合催化剂组分的方法,该预聚合催化剂组分是均匀的,并且不会粘附到干燥器的壁表面并且预聚合催化剂组分彼此聚集。 该方法包括以下步骤(1)至(4):步骤(1):将含有茂金属类化合物(B1)的溶液热处理,其通过将下述金属茂系化合物(B1)溶解于 饱和烃溶剂,在40℃以上,得到热处理材料(1); 步骤(2):将热处理材料(1)和下述金属茂系化合物(B2)的混合物在40℃以上热处理,得到热处理材料(2); 步骤(3):对上述热处理材料(2)和助催化剂载体(A)进行接触处理以获得接触处理产物(3); 和步骤(4):使接触处理产物(3)和有机铝化合物(C)进行接触处理以获得接触处理产物(4)。
