A simple method of thermal analysis is described which gives the same information as differential scanning calorimetry. The method is based on the Heat-Leak-Modulus, HLM, of a sample cell placed in a constant temperature reservoir. In the present study, the HLM method is used for the investigation of pure components and mixtures from −190 to 50 °C. The method allows the determination of glass-transition, crystallizations, solid–solid transition, eutectic, and melting temperatures with a reproducibility better than ±0.1 °C. The enthalpy of a transition can be determined with a reproducibility of ±5%. The simplicity, the low cost, and the precision of the HLM method fills the gap between standard cooling curves and sophisticated differential scanning calorimetry experiments. The HLM method has numerous applications in physical chemistry, polymer science, metallurgy, and chemical engineering.

Among the activities done under the present work are the following: - study of the kinetic regularities of the polymerization of new heterocyclic monomers and oligomers obtained from interaction between furfurylglycidyl ether and aliphatic monocarboxylic acids (saturated and unsaturated); -determination of the polymerization mechanism in the absence of complex onium catalysts; -determination of the structure and composition of monomeric and polymeric compounds by using chemical and physicochemical techniques and 1Н-NМR spectral analysis. The kinetic regularities for polymerization have been studied using Differential Scanning Calorimetry (DSC); study of the thermal resistance and thermal stability employed the derivatography techniques (DTA and TGA).
