Thermal analysis techniques have been applied to investigate many aspects of concrete science and technology. They include hydration kinetics, mechanism of hydration, deterioration of concrete, examination of the role of newly developed admixtures, admixture detection and estimation, composition of the products, identification of new compounds, etc.

The present work is a review of a particular field of polymer science which is developing fast and is at the interface of rheology, chemical hydrodynamics, macrokinetics, and the kinetics of polymerization processes. It involves the analysis of the way the viscosity growth affects a chemical reaction, i.e. the hydrodynamic, thermal, and concentration fields during polymerization.

Nuclear reaction analysis has mostly been applied to problems in material science, where the use of isotopically enriched compounds allows the profile of a specific element to be targeted by ion beam reactions with its isotopes. For example, in the thermal oxidation of silicon, the growth kinetics and diffusion of oxygen across the Si/Si02 interface region has been studied using sequential oxidations in natural and 0 enriched oxygen gas. The differentiation between possible pathways is due to the isotopic specificity of the NRA technique. 

Topical issues on the advantages and limitations of TG-MS with respect to other evolved gas analysis techniques have recently been summarised by Raemaekers and Bart a.l0] in a review on TG-MS thermal degradation of polymers. The advantageous applications of the technique in polymer science can be extended from qualitative thermal degradation analyses to thermooxidation, structural characterisation and chemical analyses, kinetics, solid-state reaction mechanisms, chemical reactivity and curing, quantitative analyses, and finally product formulation and development. 

In the field of polymer science, the crystallization behavior of polymer blends represents a key issue for the analysis of structure-properties relationships of macro-molecular systems. The presence of the second polymer component, either in the melt or in the solid state, can infiuence the whole crystallization process of the polymer phases, thus the morphology, phase behavior, and physical/mechanical properties. The crystallization processes are controlled by several factors, which are related to equilibrium thermodynamics, kinetic aspects, thermal conditions, melt rheology, as well as chain structure and polymer/polymer interactions. In the present chapter, an overview of the thermodynamic conditions, accompanied by a description of main morphological features of blends containing one or both crystallizable components, is reported.
