    • We have developed software to simulate the development of non-equilibrium latex particle morphologies produced by seeded emulsion polymerization. The diffusion of second stage polymer radicals within seed particles controls the development of morphology in a large number of systems. Knowledge of the conditions present within the latex particles during the reaction is required in order to model this diffusion process, and this makes it necessary to first simulate the kinetics of the polymerization. The program considers both the water phase and particle phase reactions, and can simulate polymerizations carried out under either batch or semi-batch conditions. The model predictions agree well with experimental results both in terms of the polymerization kinetics and the development of particle morphology.

  • Simulation of Particle Morphology Development Under Kinetically Controlled Conditions
  • 2003

    • We have developed software, called UNHLATEXTM> KMORPH, for predicting particle morphology development under conditions of kinetic control. In order to accomplish this, one must first simulate the polymerization kinetics and as a result KMORPH has developed into a fairly complete model for seeded emulsion polymerization kinetics. The simulation takes into account both the aqueous phase and particle phase reactions and can be run under either batch or semibatch conditions. Prediction of the particle morphology is accomplished by considering the diffusive penetration of radicals into the seed particles. The radial distance where each radical undergoes termination is tabulated throughout the polymerization, and this results in a radial density distribution of termination events for the second stage polymer radicals. A prediction of the particle morphology is developed based on this distribution. The model predictions, in terms of both polymerization kinetics and morphology development, are shown to agree well with experiment.
