Characterization of Size Distribution During Continuous Emulsion Polymerization: Oscillations in Vinyl Acetate Polymerization

Particle size distributions in the continuous emulsion polymerization of vinyl acetate have been predicted theoretically and measured experimentally using online measurements of turbidity spectra and offline measurements using liquid chromatography during conditions of sustained oscillations. Particle nucleation includes the dominant micellar homogeneous nucleation. Regions of instability where massive agglomeration and reactor fouling occur …
