Abstract (EN): Concentration-dependent phase separation into two polymer-containing liquid phases has been studied for the polymer pair poly(ethylene glycol) and dextran. Below the point of phase separation, the light scattering of polymer mixtures was considerably greater than for single polymers in solution. Also the viscosity of polymer mixtures was larger than the sum of the viscosity increments of polymer solutions. On the other hand, both heat capacity and density were additive in the one-phase region. The possible solvent structure in mixed polymer solutions is discussed.
