Title (EN) PROCESS FOR PRODUCING POLYMER COMPOSITIONS HAVING MULTIMODAL MOLECULAR WEIGHT DISTRIBUTION
(FR) PROCÉDÉ POUR LA PRODUCTION DE COMPOSITIONS DE POLYMÈRES AYANT UNE DISTRIBUTION MULTIMODALE DE LA MASSE MOLÉCULAIRE
Abstract:
(EN) A process is described for producing a multimodal polymer composition comprising a high molecular weight polymer (1) and a low molecular weight polymer (2), wherein the weight ratio of polymer (1) to polymer (2) is at a first value, x. The process comprises compounding in a first compounding stage a mixture of polymer (1) and polymer (2), wherein the weight ratio of polymer (1) to polymer (2) in the mixture is at a second value, y, such that y>x to form a first blend. Polymer (2) is then added to the first blend and the mixture of polymer (2) and the first blend is compounded in a second compounding stage to produce a second blend.
(FR) L'invention concerne un procédé pour la production d'une composition multimodale de polymères comprenant un polymère de masse moléculaire élevée (1) et un polymère de faible masse moléculaire (2), le rapport pondéral du polymère (1) au polymère (2) étant à une première valeur, x. Le procédé comprend le mélange dans une première étape de mélange d'un mélange de polymère (1) et de polymère (2), le rapport pondéral du polymère (1) au polymère (2) dans le mélange étant à une seconde valeur, y, de façon telle que y > x pour former un premier mélange. Du polymère (2) est ensuite ajouté au premier mélange et le mélange de polymère (2) et du premier mélange est mélangé dans une seconde étape de mélange pour produire un second mélange.
