Title (EN) HIGH FLOW HETEROPHASIC POLYOLEFIN COMPOSITION HAVING IMPROVED STIFFNESS/IMPACT BALANCE
(FR) COMPOSITION DE POLYOLÉFINE HÉTÉROPHASIQUE À FLUIDITÉ ÉLEVÉE PRÉSENTANT UN MEILLEUR ÉQUILIBRE RIGIDITÉ/RÉSISTANCE AUX CHOCS
Abstract:
(EN) High flow nucleated heterophasic polyolefin compositions comprising a matrix comprising a propylene homo- and/or copolymer and an elastomeric alpha-olefin copolymer phase dispersed in the matrix, which have rather high melt flow rate, improved impact strength but also an excellent impact/stiffness balance and a process for the preparation of such a heterophasic polyolefin composition, articles made therefrom and uses of the heterophasic polyolefin composition.
(FR) L'invention concerne une composition de polyoléfine hétérophasique nucléée à haut débit comprenant une matrice comportant un homopolymère et/ou copolymère de propylène et une phase copolymère alpha-oléfine élastomère dispersée dans la matrice, ladite composition ayant un indice de fluidité assez élevé, présentant une plus grande résistance aux chocs mais également un excellent équilibre résistance aux chocs/rigidité. L'invention concerne également un procédé de préparation de cette composition de polyoléfine hétérophasique, des articles fabriqués avec cette composition et les utilisations de cette composition de polyoléfine hétérophasique.
