Emulsion polymerization

Detectors on the ‘polymer side' included the MALS, viscometer, full spectrum UV/Vis, and RI detectors, as before. The ‘particle side' included a Malvern Mastersizer2000 detector, employing Mie scattering analysis from multi-angle scattering data. On the left side of figure, raw signals from the monomer/polymer side used to compute polymer mass, reduced viscosity, monomer conversion, etc, and on the right side, particle size distribution and specific surface area from the Mie scattering analysis are shown.

  • Predictive control of average molar mass and composition distributions

ACOMP allows predictive control of average molar mass and composition distributions - first step: control of free radical homopolymerization
