(FR) SOLUTION AQUEUSE D'ÉTHER-ACÉTATE DE CELLULOSE
Abstract: front page image
(EN)An aqueous composition comprising a cellulose ether acetate being at least partially dissolved in an aqueous liquid is produced in a process, wherein an aqueous liquid is mixed with a cellulose ether acetate having a degree of substitution of acetyl groups, DSAc, of from 0.05 to 0.75 and the temperature of the mixture of the cellulose ether acetate and the aqueous liquid is set to less than 10 C to at least partially dissolve the cellulose ether acetate in the aqueous liquid.
(FR)Selon l'invention, une composition aqueuse comprenant un éther-acétate de cellulose au moins partiellement dissous dans un liquide aqueux est produite au cours d'un processus dans lequel un liquide aqueux est mélangé à un éther-acétate de cellulose présentant un degré de substitution de groupes acétyle, DSAc, de 0,05 à 0,75; et la température du mélange d'éther-acétate de cellulose et du liquide aqueux est fixée à moins de 10°C pour dissoudre au moins partiellement l'éther-acétate de cellulose dans le liquide aqueux.
