Zusammenfassung:Novel polypropylene compositions comprising up to 100 mol % propylene having a m elt flow rate of 20 to 150 g/min at 230.degree.C and a total xylene solubles content between 4 and 35 wt. % are disc losed. In addition, a process for the production of the polypropylene composition in gas phase with particular aluminum/titanium ratios and cocatalyst/electron donor ratios is disclosed as well as a process for extrusion coating the polypropylene compositions and th e laminated articles prepared thereby.
