In this paper we define the dynamic properties of solutions of eight fractions of polystyrene in toluene and phenylon in dimethylformamide. Dynamic shear modulus and tangent of mechanical losses of these solutions were measured by acoustic resonance method at a frequency of 74 kHz. The dependences of the shear modulus on the polymer molecular weight and concentration of the solution have been determined.
