Title
(EN) COMPOSITION COMPRISING POLYPROPYLENE FOR INJECTION STRETCH BLOW MOLDING METHODS OF MAKING AND USING THE SAME
(FR) COMPOSITION COMPRENANT DU POLYPROPYLÈNE POUR MOULAGE PAR INJECTION-ÉTIRAGE-SOUFFLAGE, PROCÉDÉS DE FABRICATION ET D'UTILISATION DE CELLE-CI
Abstract
(EN)
A composition comprising polypropylene having a high melt strength suitable for an injection stretch blow molding (ISBM) process is provided. Such a composition includes a polypropylene (PP) copolymer having a branched structure. The PP copolymer is a random copolymer derived from propylene and at least one comonomer selected from ethylene, any C4-C8 alpha-olefin, or any combinations thereof. The composition has a melt flow index in a range of from 8 g/10 minutes to 30 g/10 minutes. A resulting fabricated article, a method of making the composition, and a method of using the composition are also provided.
(FR)
L'invention concerne une composition comprenant du polypropylène ayant une résistance à l'état fondu élevée, appropriée pour un processus de moulage par injection-étirage-soufflage (ISBM). Une telle composition comprend un copolymère de polypropylène (PP) ayant une structure ramifiée. Le copolymère de PP est un copolymère aléatoire dérivé du propylène et d'au moins un comonomère choisi parmi l'éthylène, une alpha-oléfine en C4-C8 quelconque, ou toute combinaison de ceux-ci. La composition présente un indice de fluidité compris entre 8 g/10 minutes et 30 g/10 minutes. L'invention concerne également un article fabriqué ainsi obtenu, un procédé de fabrication de la composition et un procédé d'utilisation de la composition.
