Resumo

Simulations of the free‐radical homopolymerization and copolymerization kinetics of fluoromonomers in carbon dioxide at supercritical conditions are presented. The homogeneous homopolymerization of dihydroperfluorooctyl acrylate (FOA) and the surfactant‐free precipitation copolymerization of tetrafluoroethylene (TFE) with vinyl acetate (VAc) in supercritical carbon dioxide were used as case studies. Reasonable agreement between experimental data from the literature and model predictions of monomer conversion vs. time, number and weight average molecular weights vs. conversion, and copolymer composition vs. conversion, for the above mentioned systems, was obtained.
