Abstract

Procédé de neutralisation de polymères sulfonés. Ce procédé consiste à accélerer la neutralisation des polymères sulfonés en les mettant en contact avec un gaz inerte contenant un composé hydroxyle sous forme de vapeur, sans rendre le polymère sulfoné visiblement humide. Permet une neutralisation rapide de polymères sulfonés destinés notamment à la réalisation de conteneurs pour hydrocarbures.Process for the neutralization of sulfonated polymers. This process consists in accelerating the neutralization of the sulfonated polymers by bringing them into contact with an inert gas containing a hydroxyl compound in vapor form, without making the sulfonated polymer visibly wet. Allows rapid neutralization of sulfonated polymers intended in particular for the production of containers for hydrocarbons.
