Viscosities of solutions of polystyrene in toluene were measured for concentrations up to 400 kg m ~3 at 298 K. Polymers of molecular weights ranging from 8.7 x 103 to 2.4 x 106 were used. It is observed that viscosity of the polymer solution increases with increasing concentration and molecular wei
