FUNCTIONALIZATION AND REINFORCEMENT IN THE DRY STATE AND IN THE WET STATE OF A CELLULOSIC MATERIAL BY AN OXIDIZED POLYSACCHARIDE

摘要

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