DSC studies on thermal phenomena in poly (ethylene terephthalate) (PET). Part II. DSC studies on the akzo-D04 300 type PET
Polimery 1997, No 4, 251
A Dutch-made Akzo-D04 300 PET was heated in a DSC instrument to simulate some processing and reuse steps. Two exotherms were recorded and assigned to cold crystallization. Successive heating runs were found to produce qualitative changes in the region of cold crystallization. While PET is being processed, its degree of crystallinity is inferred to become reduced.
