The effect of dextran concentration, pH, temperature, and urea on the conformation of dextran chain in saline solution were studied. Two characteristic concentrations for both dextrans were observed. One with c_1≈0.02 g/dL and second with c_2∼2 g/dL which may be related with aggregation and overlapping processes of polymer chains, respectively. The mean optical polarizability for dextran polysaccharides were discussed in relation to their radius of gyration. Preliminary results of the Faraday effect dispersion and their temperature dependence is also presented.
