The application of DSC techniques to explore the differences in the crystallization behavior of linear and cyclic polycaprolactone (PCL) model polymers will be presented. Standard DSC scans, isothermal scans and more advanced techniques like self-nucleation and successive self-nucleation and annealing (SSA) thermal fractionation will be explained in this tutorial by presenting a series of examples. The crystallization kinetics and melting point differences will be rationalized in terms of distinct morphology and supercooling values of linear and cyclic PCL lamellae.
