Time evolution of transition points in drying latex films
- 141 Downloads
The change of minimum film formation temperature (MFFT) with time was studied utilizing a temperature gradient bar. Fitting the data to a theory which assumed that particles deform due to the action of the polymer-air surface tension, the glass transition temperature, Tg, of the latex was predicted. This Tg was compared to the value obtained by differential scanning calorimetry (DSC) and good agreement was observed between the two measurements.
