Abstract

L'invention concerne la chimie. Le procédé de préparation de copolymères greffés cellulosevinylpyridines par polymérisation en greffe à radicaux libres de vinylpyridines sur la cellulose à partir d'émulsions aqueuses en présence d'un émulsifiant et d'un amorceur du type à radicaux libres est caractérisé suivant, l'invention en ce qu'on utilise à titre d'émulsifiant de l'acétate de polyvinyle partiellement saponifié contenant de 5 à 15 % en masse de groupements acétate. Les copolymères en question présentent des propriétés de résines anioniques et sont largement utilisés dans les processus d'échange d'ions, notamment pour le piégeage des ions de métaux précieux, la purification des eaux résiduaires, des sirops de sucre, etc.
