A low percentage of cyclic oligomers can be found in poly(ethylene terephthalate) (PET) from its synthesis onward. In this article, a cyclic-oligomer-free PET (COFP) obtained by solvent extraction was used to study the thermodynamics of the re-formation of cyclics from the melt. The cyclic-oligomer
