- Mechanism: The polymer chain transitions from a disordered to an ordered arrangement, releasing heat of crystallization.
- Curve characteristic: An exothermic peak (Tc) appears during cooling.
- Application value:
• Evaluate the impact of the process on the crystallization rate and crystallization temperature
• The crystallinity (Xc) can be calculated through the heat of fusion:
ΔHm⁰ represents the reference value at 100% ideal crystallinity (e.g., 293 J/g for PE).
