Abstract
This invention relates to isotactic propylene homopolymer compositions obtained from metallocene catalysis wherein the polymer has a molecular weight distribution (Mw/Mn) in the range of from about 2.5 to about 20.0. The isotactic propylene homopolymer composition may be prepared in a multiple stage polymerization process using the same metallocene component in at least two stages.
