Sažetak
Physicochemical characterization of clinical dextran samples of Yugoslav production was made and the results were compared with the specifications of clinical dextrans produced in other countries. Measurements of optical rotation, density, viscosity and light scattering were undertaken, and the kinetics of the alkaline iodine oxidation was analysed. The experiments were performed on unfractionated clinical samples and both low and high l0% fractions. For the purposes of routine determinations of molecular weight a relation between [eta] and M_w was given. It is valid for unfractionated clinical samples produced in the same way and having M_w in the range from 65, 000 to 95, 000. From our data it could be concluded that Yugoslav clinical dextran belongs to the group of clinical dextrans with lower molecular weight (Swedish and U. S. dextran)
