CA 2756510
The invention relates to a method for producing monoethylenically unsaturated glycosylamines, in which an aldehyde sugar is reacted with a primary aliphatic amine or ammonia in an aqueous medium and with the anhydride of a simple unsaturated carboxylic acid, without intermediate isolation, or aldehyde sugar is reacted directly with allylamine. The invention also relates to a method for producing polymers containing polymerised N-acylated glycosylamine groups, and to novel unsaturated N-maleinylated glycosylamine.
L'invention concerne un procédé de préparation de glycosylamines à insaturation monoéthylénique, consistant à faire réagir un aldéhyde-sucre avec une amine aliphatique primaire ou avec de l'ammoniaque dans un milieu aqueux, et avec l'anhydride d'un acide carboxylique à insaturation simple, sans isolement intermédiaire, ou à faire réagir l'aldéhyde-sucre directement avec de l'allylamine. L'invention concerne également un procédé de préparation de polymères contenant des groupes glycosylamine N-acylés polymérisés dans le polymère, ainsi que de nouvelles glycosylamines N-maléinylées insaturées.
