Abstract

L'invention concerne une composition de polyoléfines comprenant : A) de 67 % en poids à 94 % en poids d'un copolymère de propylène avec de l'éthylène dans lequel : i) la teneur en unités dérivées d'éthylène, mesurée par RMN, est comprise entre 2,7 % en poids et 5,3 % ; B) de 6 % en poids à 33 % en poids d'un copolymère de propylène-éthylène contenant de 18,2 % en poids à 36,4 % en poids d'unités dérivées d'éthylène, mesurée par RMN ; dans lequel la composition de polyoléfine résultante a : i) la teneur en unités dérivées d'éthylène, mesurée par RMN, étant comprise entre 5,4 % en poids et 10,0 % en poids ; ii) la teneur en unités dérivées d'éthylène, mesurée par RMN, dans la fraction soluble dans le xylène à 25° étant comprise entre 14,4 % en poids et 31,1 % en poids ; iii) un indice de fluidité (ISO 1133 (230 °C, 21,6 kg) allant de 0,5 g/10 min à 7,5 g/10 min ; iv) les matières solubles dans le xylène à 25 °C sont comprises entre 13,9 % en poids et 30,0 % en poids ; v) la viscosité intrinsèque, mesurée dans le tétrahydronaphtalène à 135 °C, de la fraction soluble dans le xylène à 25 °C est comprise entre 4,4 dl/g et 9,4 dl/g ; vi) la viscosité intrinsèque, mesurée dans le tétrahydronaphtalène à 135 °C, de la composition totale est comprise entre 4,0 dl/g et 9,4 dl/g ; la somme A+B étant égale à 100.
