Polymers — Polyethylene terephthalate (PET)

Polyethylene terephthalate (PET) is a semi-crystalline thermoplastic polymer with a relatively slow CrystallizationCrystallization is the physical process of hardening during the formation and growth of crystals. During this process, heat of crystallization is released.crystallization rate.

In the DSC experiments, the various levels of amorphousness (Tg 75°C-85°C) and crystallinity (recrystallization 146°C, melting 242°C) are apparent. The samples were cooled from the melt in the DSC 204 F1 Phoenix®® with the intracooler at different rates prior to the heating shown.
