Collective and Self-Diffusion of PS Microgels

TDFRS has been employed for the study of collective and self-diffusion of PS micronetwork spheres (microgels) [63] with crosslink ratios of 1 10,1 20, and 1 50 in toluene from low to high concentrations. 

The collective diffusion coefficient D, on the other hand, is very sensitive to the crosslink density, and TDFRS is well suited for its measurement since, because of the small scattering angles, there is no need to extrapolate for q— 0.
