[Problem] To provide a high molecular weight polypropylene material useful for film applications. A polymer comprising 60% by weight or more of propylene units and 4% by weight or more of units comprising ethylene and / or unsaturated monomers and a thermoplastic polymer different from the polymer, the polymer comprising: A blend having one characteristic of (iii). (I) 13 C NMR peaks corresponding to position errors at about 14.6 and about 15.7 ppm, said peaks being approximately the same intensity, (ii) a strain index S ix greater than about −1.20, ( iii) DSC curve with T me kept equal with increasing comonomer amount and T max shifted to the left.
