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 ...

Brillouin light-scattering from polymer gels

The experimental results of the Brillouin shift and width for poly(vinyl alcohol) and poly(vinyl chloride) gels as a function of gel network volume fraction have been analysed using the theory of Marqusee and Deutch for Brillouin light-scattering from polymer gels, incorporated with a new plausible assumption relating the speed of sound in the gel network with its volume fraction. It has been f...

Automated Batch Characterization of Polymer Solutions by Static Light Scattering and Viscometry

Using a programmable mixing pump, light scattering flow chamber, refractive index detector, and single capillary viscometer, the batch (unfractionated) characterization of polymers in solution has been automated. Three different schemes to produce polymer concentration gradients were used, and values for weight average mass Mw, root mean square radius of gyration ^S & , second virial coefficien...
