FUNCTIONALIZATION AND REINFORCEMENT IN THE DRY AND WET CONDITION OF A CELLULOSIC MATERIAL WITH AN OXIDIZED POLYSACCHARIDE

摘要

The invention relates to compounds, in particular based on polysaccharides which are absorbed on a cellulosic material. The present invention relates in particular to the application of such compounds as an agent for reinforcing cellulosic materials, in the wet and / or dry state. The invention relates to compounds comprising a combination of at least one polysaccharide adsorbed on a cellulosic material, said polysaccharide comprising at least two different monosaccharide units, forming first and second monosaccharide units, said second monosaccharide units being branched on a chain comprising minus said first monosaccharide units, at least some of the second monosaccharide units being non-cyclic and carrying aldehyde functions, said aldehyde functions possibly forming hemiacetal functions with hydroxy functions of the cellulosic material.
