Title (EN) POLYETHYLENE COMPOSITION
(FR) COMPOSITION À BASE DE POLYÉTHYLÈNE
Abstract: front page image
(EN)A multimodal polyethylene copolymer composition and prepared using a Ziegler Natta catalyst and having a density according to ISO 1183 at 23°C of at least 940 kg/m3 and an MFR2 according to ISO 1133 in the range of 0.05 to 10 g/10 min, wherein the composition has a swell ratio of at least 1.7 at an apparent shear rate of 14.4 s-1 and a rheological polydispersity index of at least 3.
(FR)La présente invention concerne une composition à base de copolymère de polyéthylène multimodal obtenue au moyen d'un catalyseur de Ziegler-Natta. Cette composition présente une densité selon ISO 1183 d'au moins 940 kg/m3 à 23°C et un indice de fluidité MFR2 selon ISO 1133 comprise entre 0,05 et 10 g/10 mn. Cette composition présente, d'une part un coefficient de gonflement d'au moins 1,7 pour une vitesse de cisaillement apparente de 14,4 s-1, et d'autre part un indice de polymolécularité rhéologique d'au moins 3.
