Static and dynamic light scattering from multicomponent polymer mixtures PS/PDMS/PMMA/toluene

The static and dynamic scattering properties of multicomponent polymer mixtures are examined starting from the theoretical formalism based on the random phase approximation (RPA) for multicomponent polymer mixtures in the presence of a low molecular weight solvent. The results are compared with the light scattering data reported recently by Strazielle and coworkers [1] for polystyrene/polydimethylsiloxane/polymethyl methylate/toluene mixtures. The present paper is an extension of the work published recently by these authors [2] and considers data obtained from several concentrations of PMMA. It also includes a discussion of the dynamic properties which are obtained by quasi-elastic light scattering.
