Crystallisation kinetics and melting studies

Methods for determining the crystallisation characteristics of polymer by differential scanning calorimetry are discussed, particularly in terms of their limitations. Isothermal and non‐isothermal crystallisation thermogrphs are analysed to determine crystallisation mechanism and compared with other techniques. The inadequacies of current theories of crystallisation rates are developed. Melting studies on oligomers and polymers are developed in terms of recent theories of melting, and a method suggested for quantifying the quality of crystallinity in polymeric material in terms of the averages of the lamellae thickness.
