Abstract: The invention relates to a method where the initial polysaccharide reacts with liquid ammonia at initial pressure higher than the atmospheric, and at temperatures about 25 deg.C, the quantity of the liquid ammonia being sufficient at least to wet the surface of the initial polysaccharide which is subsequently subjected to explosion. The volume represented by the polysaccharide liquid amonia system is increased explosion-type by reducing the pressure to over 5 bar. The method is particularly suitable for the activation of cellulose, guar rubber, starch and chitine and allows the cellulose modification in a new way. The activated polysaccharides show higher reactivity at lower reagent consumption in acilation, alkylation, silylation, xanthogenation and carbamoylation, the reaction processes being more homogenous. 26 claims
