Rheological Behaviour of Core-Shell Emulsion/Amine Crosslinking Process

Abstract:

Isothermal kinetics studies of thermal-induced gelation for epoxy functionalized poly(vinyl acetate) emulsion and diamine were investigated rheologically. The change in the viscoelastic material functions such as elastic storage modulus, G’, viscous loss modulus, G” and complex dynamic viscosity, η* during the gelation process was evaluated. The isothermal gelation kinetics was also analyzed using an isoconversional method that was based on replicated experimental data and model-free kinetics calculations. This isoconversional method evaluated an effective activation energy.
