Abstract
Condensation products having adhesive properties are obtained by reaction of a polyamine with at least two equivalents of an oligosaccharide or a derivative thereof. Examples of the oligosaccharide include glucose, lactose, lactobionic acid and gluconic acid. Examples of the polyamine include diethylene triamine and triethylene tetraamine. The reaction may be a direct amination of the oligosaccharide, with the formation of a glycosylamine and optional N-acylation, or a reductive amination of the oligosaccharide, a glycitylamine being obtained, or alternatively an amidation of an glyconic acid. The condensation products can be used for gluing, for example, paper, cardboard, wood, plastic or glass at low or high temperature.
