AbstractLiquid chromatographies of high and low‐molecular carbohydrates and polyethyleneglycols of different molecular masses were studied on porous microspherical cellulose. Dependence of the distribution coefficients of polymer molecules on molecular mass was determined. It was revealed that the distribution coefficient depends on the hydrodynamic diameters of the polymer molecules. The possibility of using macroporous polysaccharide gels in the liquid chromatography of polymers, in order to study carbohydrates and other water soluble polymer, was discussed.
