A METHOD FOR PREPARING SOLID CATALYST FOR PROPYLENE POLYMERIZATION, A SOLID CATALYST PREPARED BY THE SAME AND A METHOD FOR PREPARATION OF POLYPROPYLENE USING THE CATALYST |
摘要 |
The present invention provides a method for preparing a solid catalyst for propylene polymerization, a solid catalyst prepared by the same, and a method for preparing polypropylene using the solid catalyst, wherein the method for preparing a solid catalyst for propylene polymerization includes adding an internal electron donor selected from a bicyclo alkane carboxylate compound and a bicyclo alkene dicarboxylate compound twice in a preparing process of a solid catalyst for propylene polymerization. According to the present invention, provided is a solid catalyst for propylene polymerization having excellent activity and stereoregularity, showing a wide molecular weight distribution, and having high melt-flowability. |
