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 ...
متن کاملThermodynamjc 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...
متن کاملRenormalization group evaluation of the second virial coefficient of polydisperse polymer solutions
2014 The second virial coefficient A2 for a mixture of two monodisperse polymers is studied by means of the renormalization group. It is found that the cross-term A12 has a finite limit if the segment number of one of the polymers tends to infinity. Such behaviour predicts a maximum of A2 in dependence on the relative composition of the polymers. The maximum resulting from our firstorder RG-cal...
متن کاملHaldane exclusion statistics and second virial coefficient.
We show that Haldanes new definition of statistics, when generalised to infinite dimensional Hilbert spaces, is equal to the high temperature limit of the second virial coefficient. We thus show that this exclusion statistics parameter, g , of anyons is non-trivial and is completely determined by its exchange statistics parameter α. We also compute g for quasiparticles in the Luttinger model an...
متن کاملNonmonotonic variation with salt concentration of the second virial coefficient in protein solutions.
The osmotic virial coefficient B2 of globular protein solutions is calculated as a function of added salt concentration at fixed pH by computer simulations of the "primitive model." The salt and counterions as well as a discrete charge pattern on the protein surface are explicitly incorporated. For parameters roughly corresponding to lysozyme, we find that B2 first decreases with added salt con...
