Title (EN) PROCESS FOR PRODUCING POLYMER BLEND
(FR) PROCESSUS DE PRODUCTION DE MÉLANGE POLYMÈRE
Abstract:
(EN) The invention relates to a process for producing a blend of a thermoplastic starch and a polyolefin using a first extruder comprising successive zones comprising a first zone, a second zone, a third zone and a fourth zone and a second extruder comprising successive zones comprising a first zone, a second zone, a third zone and a fourth zone, the process comprising the steps of: 1 a) introducing a polyolefin and a compatibilizer in the first zone of the first extruder, 1 b) melt mixing the polyolefin and the compatibilizer in the second zone of the first extruder, 1 c) adding a thermoplastic starch to the mixture of step 1 b) in the third zone of the first extruder and 1 d) melt-mixing the mixture of step 1 c) in the fourth zone of the first extruder to obtain the blend, wherein the thermoplastic starch is produced in the second extruder by a process comprising the steps of: 2a) introducing starch in the first zone of the second extruder, 2b) adding a plasticiser to the mixture of step 2a) in the second zone of the second extruder to obtain the thermoplastic starch, 2c) degassing the thermoplastic starch of step 2b) in the third zone of the second extruder and 2d) pressurizing the degassed thermoplastic starch of step 2c) in the fourth zone of the second extruder to be moved to the third zone of the first extruder.
(FR) L'invention concerne un procédé de fabrication d'un mélange d'un amidon thermoplastique et d'une polyoléfine à l'aide d'une première extrudeuse comprenant des zones successives comprenant une première zone, une deuxième zone, une troisième zone et une quatrième zone et une deuxième extrudeuse comprenant des zones successives comprenant une première zone, une deuxième zone, une troisième zone et une quatrième zone, le processus comprenant les étapes consistant à : 1a) introduction d'une polyoléfine et d'un agent de compatibilité dans la première zone de la première extrudeuse, 1 b) mélange à l'état fondu de la polyoléfine et de l'agent de compatibilité dans la seconde zone de la première extrudeuse, 1c) ajout d'un amidon thermoplastique au mélange de l'étape 1 b) dans la troisième zone de la première extrudeuse et 1d) mélange à l'état fondu du mélange de l'étape 1 c) dans la quatrième zone de la première extrudeuse pour obtenir le mélange, l'amidon thermoplastique étant produit dans la seconde extrudeuse par un processus comprenant les étapes consistant à : 2a) introduction de l'amidon dans la première zone de la deuxième extrudeuse, 2b) ajout d'un plastifiant au mélange de l'étape 2a) dans la deuxième zone de la deuxième extrudeuse pour obtenir l'amidon thermoplastique, 2c) dégazage de l'amidon thermoplastique de l'étape 2b) dans la troisième zone de la deuxième extrudeuse et 2d) mise sous pression de l'amidon thermoplastique dégazé de l'étape 2c) dans la quatrième zone de la deuxième extrudeuse pour être déplacée vers la troisième zone de la première extrudeuse.
