Sur les propriétés hydrodynamiques des solutions de grandes molécules en chaîne I. Dimensions et viscosité du polystyrène dans différents solvants

Abstract

Abstract Polystyrene fractions over a wide range of molecular weights have been studied by osmotic pressure, viscosity and light scattering in different solvents. The hypothesis of the equivalent hydrodynamic sphere has been verified. The interpretation of the viscosity results as a function of the solvent has been possible in accordance with Flory's theory of real configuration of chain molecules in solution.
