Abstract
The present invention relates to a method for producing a propylene polymer having a very high melt flowability, specifically to a method for producing an isotactic propylene polymer having a dramatically improved melt flowability with a relatively high production yield in convenient way, by improving the reactivity of hydrogen that is served as a molecular weight controlling agent in propylene polymerization.
