Abstract:
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.
