Title (EN) PROCESS FOR PREPARING POLYPROPYLENE COMPOSITION
(FR) PROCÉDÉ POUR LA PRÉPARATION D'UNE COMPOSITION DE POLYPROPYLÈNE
Abstract:
(EN) The invention relates to a process for producing a polypropylene composition by sequential polymerization, said polypropylene composition having low sealing initiation temperature (SIT) and high melting point (Tm), thus providing a broad sealing window.
(FR) L'invention concerne un procédé pour la production d'une composition de polypropylène par polymérisation séquentielle, ladite composition de polypropylène ayant une faible température d'initiation de scellage (SIT) et un point de fusion élevé (Tm), fournissant ainsi une large fenêtre de scellage.
