Evaluation of the compressional compliance of a polymer melt from dynamic light scattering data using linear viscoelastic relations

The method of determining the compressional (or bulk) compliance by using the dynamic light scattering spectrum arising from density fluctuations has been evaluated. It is also shown by numerical computation for cases where the relaxation function can be described by a single Williams-Watts function...

Zusammenfassung:	The method of determining the compressional (or bulk) compliance by using the dynamic light scattering spectrum arising from density fluctuations has been evaluated. It is also shown by numerical computation for cases where the relaxation function can be described by a single Williams-Watts function that the numerical technique used to compute the retardation spectrum also gives an identical result.
