A Hydrodynamic Invariant of Polymeric Molecules

Theories of the hydrodynamic properties of macromolecules in solution are examined, from which the invariant relation A₀ = kη₀(M[η]/100)^1/3f can be obtained between the intrinsic viscosity [η] , the molecular mass M, and the coefficient of sliding friction of the molecule f. Analysis of the experimental results will indicate the most probable values of the invariant A₀ for various classes of polymers. A list of 314 references is included.
