Abstract

The invention comprises a process for amidating material which comprises at least one carboxyl-containing polysaccharide. The process comprises a first step, in which the carboxyl groups are reacted with an ammonium donor of the general formula >NH in order to form the corresponding polysaccharide carboxylammonium salt, and a second step, in which the polysaccharide carboxyl- ammonium salt is heated in order, in this way, to convert the ammonium groups into corresponding amido groups. The invention also relates to fatty amide-modified carboxyl- containing polysaccharides and, in particular, fatty amide-modified carboxymethyl cellulose. The products according to the invention can be used extensively, for example in biodegradable plastics, as anti-waste deposition agents for synthetic fibres, as polymer emulsifying agents, as pigment dispersing agents, in cosmetic products, as thickeners, as oil drilling liquids, as superabsorbers and in mineral processing.
