Abstract: The ethers are prepared by reacting alkylene epoxides with cellulose or derivatives thereof in alkaline medium in the presence of water. Cationisation agents employed are alkylene epoxides or mixtures thereof with the general formulae in which n is 1, 2 or 3, R , R and R are identical or different alkyl radicals with 1 to 18 carbon atoms or R is the benzyl radical or -C2H4OH, and X is chloride, bromide, sulphate or acetate.
