The result of the synthesis and investigation of FTIR spectra of some dextran sulphates and their sodium (Na) salts are presented. A synthesis was conducted (under different reaction parameters) of esters with various degrees of esterification (from 1.0 to 2.3). FTIR investigations were performed on sulphates of low and high molecular hydrogenated dextrans of various molecular masses (Mw of 5000, 7000, 8000, 40000 and 5). Particular care was taken to determine the degree of linearity of the synthesized dextran sulphates, the conformation of glucopyranosyl units and the way the sulpho groups and the water were bonded in their structures.
