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.
A compound comprising an association 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 at least said first monosaccharide units, at least some of the second monosaccharide units being non-cyclic and bearing aldehyde functions, said aldehyde functions possibly forming hemiacetal functions with hydroxy functions of the cellulosic material, said polysaccharide is also covalently bonded by one or more reactive molecules reacting with aldehyde functions of the polysaccharide.
