Abstract
On décrit un procédé de préparation de copolymères solubles dans l'eau d'acides carboxyliques vinyliques et d'acrylates d'alkyle inférieur, utilisant un réacteur tubulaire et polymérisant les monomères en solution aqueuse en présence d'un catalyseur radicalaire. On obtient, en utilisant ce procédé, des poids moléculaires de 3 000 à 300 000 et, de préférence, d'environ 5 000 à 25 000.
