Beschreibung
Zusammenfassung:	The present invention relates to a method for producing a solid catalyst component for alpha-olefin polymerization by bringing components (A1) to (A4) into contact with each other in an inert solventand, without washing such contact product with the inert solvent, allowing the contact product to stand and age for a waiting time of 3-180 days from the point at which all of the components (A1) to (A4) first come into contact with each other. Component (A1): a solid component containing titanium, magnesium, a halogen and an electron-donating compound as essential components. Component (A2): an alkenyl group-containing silane compound. Component (A3): an alkoxyl silane compound. Component (A4): an organic aluminum compound. 本发明涉及种α-烯烃聚合用固体催化剂组分的制造方法，其通过以下来进行：使组分(A1)至(A4)在惰性溶剂中彼此接触，和不用惰性溶剂洗涤接触产物，从所述组分(A1)至(A4)全部首次接触的时间点起使接触产物静置3-180天的保持时间来熟化。组分(A1)：包含钛、镁、卤素和供电子性化合物作为必要组分的固体组分；组分(A2)：含烯基的硅烷化合物；组分(A3)：烷氧基硅烷化合物；组分(A4)：有机铝化合物。
