Abstract
The present disclosure provides a suspension of a solid catalyst component used in propylene polymerization and a method for preparing the same. The suspension includes the solid catalyst component and a liquid medium containing propylene and an alkane, and is preferably prepared by mixing the solid catalyst component and the alkane to obtain a mixed slurry, which is further mixed with liquid propylene. Using of a proper liquid dispersing agent at a proper proportion and amount enables the solid catalyst component to be more homogeneously dispersed, thus preventing the phenomenon of agglomeration in the polymerization process without using a large amount of the dispersing agent or any additional mixer. The present disclosure further provides a method of propylene polymerization, including feeding the suspension into a reaction system of propylene polymerization, wherein propylene polymerization is initiated under polymerization conditions.
