Glass transition, cold crystallization, premelt crystallization, and melting in polyethylene terephthalate and copolyesters have been studied by differential thermal analysis. The transitions are affected by changing the chemical composition of the polyesters through replacing one monomer partially or completely with a different monomer. Quenching, annealing, and/or drawing, which render different degrees of crystallinity to a polyester, can also be detected directly from the thermograms.
