The present invention relates to a propylene polymerizing solid catalyst for reducing the volatile organic compound (VOC) and a method of producing polypropylene using the propylene polymerizing solid catalyst, the propylene polymerizing solid catalyst including an organic electron donor formed of a combination of a first internal electron donor of titanium, magnesium, halogen and cyclic diester and a second internal electron donor of diether, and has improved hydrogen reactivity of a catalyst compared to a conventional method and has an effect that is capable of producing an eco-friendly polypropylene which has greatly lowered a content of the VOC by using the catalyst.

Propylene polymerizing solid catalyst for reducing VOC and method of producing polypropylene using same

The present disclosure relates to a solid catalyst for propylene polymerization and a process for manufacture of a propylene polymer or copolymer using the solid catalyst, and provides a solid catalyst including carriers produced via a reaction between dialkoxy magnesium and metal halide, titanium halide, an organic electron donor, etc. and a process of manufacture of a propylene-based block copolymer via copolymerization of propylene-&#x3b1;-olefin using the solid catalyst. Particularly, internal electron donors including an ester group and an alkoxy group are used as two kinds of organic electron donors used in the present disclosure, and, thus, a block copolymer having high activity and excellent stereoregularity and a high rubber content via copolymerization with &#x3b1;-olefin can be produced using a solid catalyst system suggested in the present disclosure.
