- Experimental evaluation of dependent light scattering model for bidisperse systems.
- Successful particle sizing in highly concentrated bidisperse polymer dispersions.
- Relative amount of small and large particles is successfully obtained.
Photon Density Wave (PDW) spectroscopy is applied for characterizing the scattering properties, i.e. the reduced scattering coefficient μsâ², of highly concentrated mono- and bidisperse polymer latices. The theory for dependent scattering is reviewed and analytical expressions for the structure factors for hard sphere interaction in mono- (HSPYA) and bidisperse (BHSPYA) systems are given. From the scattering properties particle sizes of mono- and bidisperse polystyrene latices are determined as well as the relative amount of small and large particles for the bidisperse case.
