Abstract:
Disclosed is a method for producing a propylene polymer using an alkoxysilane compound comprising a trialkylsilyl group in its molecular structure, specifically a method for easily producing an isotactic propylene polymer with dramatically improved melt flowability, owing to the improved reactivity of hydrogen that is provided as a molecular weight regulator, by specifically using an alkoxysilane compound comprising a trialkylsilyl group in the molecular structure thereof as an external electron donor in propylene polymerization.
