Johanna K. DiStefano,Christopher B. Kingsleyn, differential scanning calorimetry was used to measure the melting point depressions of mixtures of the polymer with 1-chloronaphthalene, and from these data the heat and entropy of fusion were calculated.

Mohamed Derouich,Mohamed E. N. Lamlilif 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.. At present, there is no evidence of the existence of polymorphic crystalline modifications in poly (ethylene terephthalate).

Ibrahim Hanouneh M.D.,Bijan Eghtesad M.D. temperature dependence of the viscosity and heat capacity in the region of 159°C and the solubility or lack of solubility of various forms of S in solvents such as CS.. Further, the structures of the highly molecular crystalline phases of S and Se have strongly influenced thought on the possible molecular forms in the liquid.

Measurement of the Heat of Fusion of Crystalline Polymers by a Calorimetric Melting Point Depressionthalpic base line is drawn. This temperature is generally well above the temperature at which independent measurements of the degree of crystallinity are made, and heat of fusion values obtained via this technique are no more accurate than the percent crystallinity values used in the calculation.
