Abstract (en)
[origin: WO0132757A1] This invention relates generally to foamable polypropylene polymer, and more particularly to a foamable isotactic polypropylene homopolymer obtained from metallocene catalysis and to their methods of production and articles formed therefrom. The foamable polypropylene polymer has molecular weight distributions and densities that fall within broad ranges. The foamable polypropylene polymer may be prepared in a multiple stage polymerization process using the same metallocene component in at least two stages.
