Abstract

L'invention divulgue une composition de résine de polypropylène, qui est un polypropylène comportant des ramifications à chaînes longues et présentant une excellente viscosité en extension, de nombreuses ramifications sur la chaîne principale de polypropylène et un degré élevé de ramification à chaînes longues. La présente invention concerne une composition de résine de polypropylène (B) présentant un poids moléculaire moyen en poids compris entre 310 000 et 550 000 g/mol, une distribution de poids moléculaires (MWD, Mw/Mn) comprise entre 5,5 et 7, une viscosité en extension comprise entre 1600 et 5000 kPa·s, une teneur en gel inférieure à 5 % en poids, un indice de ramification supérieur ou égal à 20, et un degré de ramification à chaînes longues d'au moins 0,06.
