Polysaccharides are functionalized using a source of free radicals which forms stable radicals on the polysaccharides structure and wherein the formed radicals reacts with a functionalized unsaturated compound. The method comprises two steps: a first step, wherein the free radical on the polysaccharides chain is formed, and a second step, wherein said radical reacts with the unsaturated compound in the absence of the radical source.
