Abstract (en)
[origin: FR2762603A1] The invention concerns reactive cellulose, i.e. having in particular a very low degree of crystallinity obtainable with a high degree of purity. Said novel reactive cellulose is particularly used as raw material for making cellulose ethers. The invention is characterised in that the reactive cellulose is substituted by organic groups according to a degree of substitution DS less than 0.2, advantageously ranging between 0.04 and 0.2.
