Abstract (en)

[origin: WO9320115A1] Novel propylene compositions having a melt flow rate of 0.1 to 20 g/10 min at 230 DEG C and specified levels of crystallinity are disclosed. In addition, a process for the production of the polypropylene composition in gas-phase or slurry-phase at a temperature of 75 to 90 DEG C hydrogen/propylene ratios, with particular aluminum/titanium ratios, and cocatalyst/electron donor ratios is disclosed as well as a process for extruding the polypropylene compositions and the articles prepared thereby.
