Quasi-elastic scattering by dilute, ideal, polymer solutions: II. Effects of hydrodynamic interactions

On the nature of the slow modes appearing in quasi-elastic light scattering by semi-dilute polymer solutions

2014 We describe three series of experiments of quasi-elastic light scattering by semi-dilute solutions of polymers. By varying parameters such as the concentration, molecular mass, polymer structure, and the time interval between the solution preparation and the time of measurement, we are able to rule out a number of hypothesis about slow modes and to propose a qualitative interpretation of t...

Light scattering by cooperative diffusion in semi-dilute polymer solutions

2014 We report measurements of relaxation times of the autocorrelation function for the Rayleigh line of light scattered by semi-dilute polymer solutions. LE JOURNAL DE PHYSIQUE LETTRES TOME 37, MARS 1976 Classification Physics Abstracts 7.146-7.221-7.610-5.660 Recent observations of polymer diffusive motions by light scattering have dealt with two extreme situations : the very dilute solution ...

Thermodynamjc Interactions in Dilute Polymer Solutions: the Virial Coefficients

The statistical thermodynamics of dilute polymer solutions is reviewed from the point of view of the continuum theory based on molecular distribution functions. The comparatively rigorous perturbation treatment of the second and third virial coefficients, and various approximate theories derived from it to give closed-form expressions useful for good-solvent systems. are outlined. Indications f...
