A new method was developed to study the alcoholysis ofEVA with 32 mol% ethylene content based on in situ FTIR spectroscopy. Thefeasibility and accuracy of this method was carefully studied. A kinetic modelfor predicting reaction rate was obtained using this method. The applicabilityof the kinetic model was further verified by performing flow alcoholysis inmicroflow reactor.


  • Established an efficient method based on in situ FITR spectroscopy to investigate EVA alcoholysis.

  • Studied the kinetics of EVA alcoholysis catalyzed by alkaline systematically.

  • Obtained a kinetic model of EVA alcoholysis capable for reaction process prediction.

  • Achieved fast and controlled alcoholysis of EVA in a microflow system.
