Prediction and analysis of nonisothermal crystallization of polymers

Interplay between Chain Relaxation Time and Melt Crystallization Time in Microinjection Molding of Polyoxymethylene

“…Figure shows the onset temperatures of crystallization as a function of the cooling rate. The decrease of the crystallization temperature ( T c ) with increasing cooling rate is minor up to around 800 K s –1 , while it becomes more distinct on cooling at rates higher than 1000 K s –1 , being consistent with data in the literature. ,− …”

Glass Forming Ability of Amorphous Drugs Investigated by Continuous Cooling and Isothermal Transformation

“…Additionally, there is a tendency to obtain a higher degree of supercooling the higher the applied cooling rate. This was also found in previous studies, but as a general statement this is only true if the recrystallization mechanism does not change upon cooling. , Close to the melting point, heterogeneous nucleation governs the overall recrystallization, but with increasing supercooling, the importance of homogeneous nucleation increases . Furthermore, if the thermodynamic driving force is much higher than the kinetic driving force, onset of recrystallization will not be cooling rate dependent, which was also seen for drugs with poor GFA …”

Opposite role of different carbon fiber reinforcements on the non-isothermal crystallization behavior of poly(etheretherketone)

“…Kinetic aspects of the crystallization process were usually described by the Avrami theory or alternative methods [14,16,17], but studies performed so far are often discordant and most models were proven to be inadequate to some extent, especially when considering the addition of reinforcements [3,7,18,19], to the point that no clear indication on the effect of the reinforcement on the crystallization behavior of the polymer can be obtained.…”
