A solid catalyst component for polymerization of olefins prepared by allowing a titanium halide, a diester of aromatic dicarboxylic acid and a dialkoxymagnesium having a bulk density of at least 0.25 g/mℓ to come in contact with one another and a catalyst comprising said solid catalyst component. The use of said catalyst makes it possible to efficiently obtain a polyolefin having a high stereoregularity, a high bulk density and excellent particle properties.
一种用于烯烃聚合的固体催化剂组分,其制备方法是让卤化钛、芳香族二羧酸二酯和体积密度至少为 0.25 g/mℓ 的二烷氧基镁相互接触,以及使用包含所述固体催化剂组分的催化剂。通过使用上述催化剂,可以有效地获得具有高立体规整度、高容积密度和优异颗粒特性的聚烯烃。
