A solid catalyst component for olefin polymerization makes it possible to polymerize an olefin with high polymerization activity when used for an olefin polymerization catalyst, and produce an olefin polymer having a low fine powder content, a low coarse powder content, and a low volatile organic compound (VOC) content in high yield. The solid catalyst component for olefin polymerization is produced by suspending (a) a dialkoxymagnesium, and (b) at least one alcohol selected from ethanol, n-propanol, n-butanol, isopropanol, isobutanol, and t-butanol, in an inert organic solvent so that the total amount of the alcohol is 0.5 to 1.5 parts by mass based on 100 parts by mass of the dialkoxymagnesium, to prepare a suspension, and bringing (c) an internal electron donor and (d) a titanium halide compound into contact with the suspension.
一种用于烯烃聚合的固体催化剂组分可使烯烃聚合催化剂具有较高的聚合活性,并能高产率地生产出细粉含量低、粗粉含量低和挥发性有机化合物(VOC)含量低的烯烃聚合物。用于烯烃聚合的固体催化剂组分是通过在惰性有机溶剂中悬浮 (a) 二羰基镁和 (b) 至少一种选自乙醇、正丙醇、正丁醇、异丙醇、异丁醇和正丁醇的醇,使醇的总量为 0.5 至 1.5 质量份(以 100 质量份的二烷氧基镁为基准),以制备悬浮液,并使(c) 内部电子供体和(d) 卤化钛化合物与悬浮液接触。
