description | A process to prepare a polypropylene, and the polypropylene and films therefrom, comprising combining a high melt strength polypropylene comprising at least 50 mol % propylene, and having a molecular weight distribution (Mw/Mn) greater than 6, a branching index (g′vis) of at least 0.95, and a melt strength of at least 20 cN determined using an extensional rheometer at 190° C., and within the range from 20 to 1000 ppm of a long half-life organic peroxide, and isolating the polypropylene, wherein the polypropylene thus formed has a molecular weight distribution (Mw/Mn) within a range of from 7 to 22, a z-average molecular weight of less than 1,600,000 g/mole, a branching index (g′vis) of at least 0.95; and a melt strength less than 20 cN. |
