Abstract: The present disclosure relates to a catalyst composition for polymerizing propylene and a method for producing polypropylene. The catalyst composition for polymerizing the propylene includes a modifying agent. The modifying agent is an ester compound having hydrophilic groups and hydrophobic groups. In the method for producing the polypropylene, a reverse microcellular structure is formed by the modifying agent during a propylene polymerization, in which the hydrophilic groups are inside the reverse microcellular structure, and the hydrophobic groups are outside the reverse microcellular structure, such that polar substances in a raw material are retained inside the reverse microcellular structure. Thus, poisoning of the catalyst is reduced. Besides, the modifying agent can maintain a valence state of titanium in an active site of the catalyst at positive trivalent, such that the propylene polymerization between the titanium and the monomer is facilitated, thereby enhancing an activity of the catalyst.
