Crystallization of Poly(ethylene terephthalate)

It has been reported that several endothermic melting transitions exist in differential thermal analysis thermograms of polyethylene.1 Similar transitions are reported in differential scanning calorimetric thermograms of poly (ethylene terephthalate)2 and bisphenol-A polycarbonate.3 The appearance of separate melting endotherms in these polymers is evidence that almost completely discontinuous distributions of crystallite sizes or perfections can be induced in a polymer by appropriate thermal treatments.4 At present, there is no evidence of the existence of polymorphic crystalline modifications in poly (ethylene terephthalate).
