Abstract
The present invention relates to a preparation method for polypropylene that comprises polymerizing a propylene monomer in the presence of a catalyst comprising a novel transition metal compound. Using the novel transition metal compound as a catalyst, the preparation method for polypropylene according to the present invention can not only acquire high catalytic activity for polymerization to achieve high efficiency of the process but allow it to easily control the fine-structure characteristics of the polymer, thereby providing polypropylene having desired properties with ease.
