Crystallization from melt of poly(vinylidene fluoride) was studied by thin film chip calorimetry at cooling rates from 500 to 100,000 Ks(-1) and isothermally down to 76 degrees C. At ca. 70 degrees C, for cooling rates higher than 2000 Ks(-1), there appears a change in crystallization from high temperature alpha phase to low temperature beta phase. The amorphous state is preserved at cooling rate 100,000 Ks(-1). Analysis of the crystallization kinetics with Ziabicki model reveals maximum of the steady-state crystallization rate of beta phase as 2200 s(-1) at 22 degrees C, and the highest crystallization rate of alpha phase as 200 s(-1) at 70 degrees C. Approximation of the temperature dependent steady-state crystallization rate with the Turnbull and Fisher nucleation model results in the equilibrium melting temperatures 227 and 173 degrees C for the alpha and beta phase, respectively, and in the energy barrier for short-distance transport, E-D, as 70-80 kJ mol(-1) at high supercooling.
