Title
(EN) POLYPROPYLENE IMPACT COPOLYMERS HAVING HIGH MELT FLOW AND IZOD DUCTILITY
(FR) COPOLYMÈRES RÉSISTANTS AU CHOC DE POLYPROPYLÈNE AYANT UN INDICE DE FUSION ÉLEVÉ ET UNE DUCTILITÉ IZOD ÉLEVÉE
Abstract
(EN)
Impact copolymers that comprise a continuous phase comprising a propylene-based polymer and a discontinuous rubber phase comprising a propylene/ethylene copolymer. The impact copolymers can have a fraction copolymer value (Fc) of at least 35, an ethylene content (Ec) of at least 38, a melt flow rate of at least 50 g/10 min and a notched Izod impact strength at 23 C of at least 615 J/m.
(FR)
Des copolymères résistants au choc comprennent une phase continue comprenant un polymère à base de propylène et une phase discontinue de caoutchouc comprenant un copolymère propylène/éthylène. Les copolymères résistants au choc peuvent avoir une valeur de copolymère de fraction (Fc) d'au moins 35, une teneur en éthylène (Ec) d'au moins 38, un indice de fusion d'au moins 50 g/10 et une résistance au choc Izod sur barreau entaillé à 23°C d'au moins 615 J/m.
