Evaluation
PVF is semi-crystalline and shows, along with a glass transition at approx. 39°C in the 2nd heating (green, midpoint), a melting transition with a peak temperature of 195°C (2nd heating). The melting enthalpy of approx. 56 J/g was similar in the two heatings.
The glass transition steps with 0.07 J/(g.K) (1st heating, blue) and 0.09 J/(g.K) (2nd heating, green) are very small.
The glass transition steps with 0.07 J/(g.K) (1st heating, blue) and 0.09 J/(g.K) (2nd heating, green) are very small.
