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 20Ø The isotactic propylene homopolymer composition may be prepared in a multiple stage polymerization process using the same metallocene component in at least two stages.

Cette invention porte sur des compositions d'homopolymères de propylène isotactiques obtenues à partir de la catalyse du métallocène. La répartition (Mw/Mn) des poids moléculaires du polymère est comprise entre environ 2,5 et environ 20,0. La composition d'homopolymères de propylène isotactiques peut être préparée selon un procédé de polymérisation en plusieurs étapes au moyen du composant métallocène précité, et au moins en deux étapes.
