PROCESS FOR REMOVING VOLATILE COMPONENTS FROM AN OLEFIN POLYMER AND ARTICLE OBTAINED
(FR)
PROCÉDÉ D'ÉLIMINATION DE COMPOSANTS VOLATILS D'UN POLYMÈRE D'OLÉFINE ET ARTICLE OBTENU
Abstract:
(EN)
The invention relates to a process for removal of volatile components from an olefin polymer, the process carried out in an extruder comprising at least one vacuum degassing zone, said process comprising the steps of: (a) introducing a stream of an olefin polymer into the extruder; (b) extruding the olefin polymer in the extruder at a temperature which is higher than the melting temperature of the olefin polymer but lower than the decomposition temperature of the olefin polymer, thereby producing an olefin polymer melt having reduced amount of volatile components, wherein the process in the extruder has a residence time distribution broadness (σ2) in the range of 800 to 4000 as define by equation (1) wherein: σ2 is the residence time distribution broadness, T is the mean residence time, t is the interval of residence time a fluid element of the olefin polymer spends in the extruder, E(t) is the residence time distribution function, and wherein the process optionally comprises a step (c) where the melt of the olefin polymer is passed through a die zone to a pelletizer for pelletizing the obtained olefin polymer.
(FR)
L'invention concerne un procédé d'élimination de composants volatils d'un polymère d'oléfine, le procédé étant mis en oeuvre dans une extrudeuse comprenant au moins une zone de dégazage sous vide, ledit procédé comprenant les étapes consistant à : (a) introduire un flux d'un polymère d'oléfine dans l'extrudeuse ; (b) extruder le polymère d'oléfine dans l'extrudeuse à une température qui est supérieure à la température de fusion du polymère d'oléfine mais inférieure à la température de décomposition du polymère d'oléfine, ce qui permet de produire une masse fondue de polymère d'oléfine ayant une quantité réduite de composants volatils, le procédé dans l'extrudeuse ayant une largeur de distribution de temps de séjour (σ2) dans la plage de 800 à 4 000 telle que définie par l'équation (1) dans laquelle : σ2 est la largeur de distribution de temps de séjour, T est le temps de séjour moyen, t est l'intervalle de temps de séjour qu'un élément fluide du polymère d'oléfine passe dans l'extrudeuse, E(t) est la fonction de distribution de temps de séjour, et le procédé comprenant facultativement une étape (c) dans laquelle la masse fondue du polymère d'oléfine est passée à travers une zone de filière vers un granulateur pour granuler le polymère d'oléfine obtenu.
