Monodisperse latex particle size analysis

Seed Characterization. A monodisperse seed latex of known initial diameter is required if continued seed growth by second stage polymers is to be unambiguously measured by particle size analysis. The seed recipes selected were known to give uniform sized particles (14,15). All five of the latexes were monodisperse as measured by JLDC (Table II) and exhibited a character-... 

Figure 5.15 shows an example of a correlation function measured for a sample consisting of monodisperse latex beads. For a polydisperse sample (i.e., particles with a size distribution), the analysis of scattering data is more complicated, but the molecular weight distribution can be determined by modeling the correlation function as the sum of the contributions from different discrete molecular weights.
