Abstract:
(EN) A film comprising a polypropylene composition comprising: A) from 50 wt% to 90 wt%; of a propylene homopolymer; B) from 10 wt% to 50wt%; of a copolymer of propylene with from 30.0 wt% to 70.0wt%, of ethylene derived units; the sum of the amount of component A) and B) being 100; the composition having: i) an intrinsic viscosity of the fraction soluble in xylene at 25 °C comprised between 2.2 and 4.0 dl/g; ii) a MFR L (Melt Flow Rate according to ISO 1133, condition L, i.e. 230°C and 2.16 kg load) from 0.5 to 50 g/10 min; iii) a xylene soluble fraction ranging from 20 wt% to 50 wt%; the polypropylene composition being obtained by a two steps polymerization process wherein the catalyst system contains bismuth.
(FR) L'invention concerne un film comprenant une composition de polypropylène comprenant : A) de 50 % en poids à 90 % en poids; d'un homopolymère de propylène; B) de 10 % en poids à 50 % en poids, d'un copolymère de propylène avec 30,0 % en poids à 70 % en poids de motifs dérivés de l'éthylène; la somme de la quantité des constituants A) et B) étant de 100; la composition ayant : i) une viscosité intrinsèque de la fraction soluble dans le xylène à 25 °C comprise entre 2,2 et 4,0 dl/g; ii) un MFR L (indice de fluidité à chaud selon la norme ISO 1133, condition L, soit 230 °C et une charge de 2,16 kg) de 0,5 à 50 g/10 min; iii) une fraction soluble dans le xylène comprise entre 20 % en poids et 50 % en poids; la composition de polypropylène étant obtenue par un procédé de polymérisation en deux étapes, le système de catalyseur contenant du bismuth.
