The definition proposed in 1991 in the ICTAC booklet For Better Thermal Analysis and Calorimetry [10] was as follows ... 

The nomenclature for thermal analysis and calorimetry is presently under review, so that recent developments and calorimetric methods may be included. The recommendations approved by the ICTA Council and by lUPAC are reported by Dr Robert C. Mackenzie in Treatise on Analytical Chemistry, Part 1, Vol. 12, Section J, ed. P. J. Hiving, Wiley, New York, 2nd edn., 1983. A provisional version was also given in For Better Thermal Analysis and Calorimetry, ed. J. O. Hill, ICTA, Edition III, 1991. However, this has not been approved by ICTA Council. A further revision is in preparation.

MetastabiUly - a common feature in both macromolecular and pharmaceutical systems - is a second major challenge for the coming years. For a thorough understanding of die kinetics of all lands of temperature- and time-dependent processes related to metastability, there is now an urgent need for new and better-matching thermal analysis and calorimetry techniques. 

The recommended nomenclature has been put forward by the International Nomenclature Committee of the International Confederation for Thermal Analysis and Calorimetry (ICTAC). These recommendations are widely circulated in publications of the confederation and the International Union of Pure and Applied Chemistry (lUPAC). The most widely publicized report is the booklet For Better Thermal Analysis, which is continually updated as required. 

A novel process for the preparation of latex with high solid content, but maintaining the characteristics of microemulsion polymerisation latex, small particle size (less than 50 nm) and polymer with high molecular weight (more than 10 6) is presented. With the PS latex obtained by microemulsion polymerisation as seed, core shell, styrene-butyl acrylate polymers functionalised with itaconic acid are prepared. Materials were characterised by differential scanning calorimetry, dynamic mechanical thermal analysis and transmission electron microscopy. These polymers have better mechanical properties than the non functionalised or those prepared by emulsion polymerisation. 11 refs. 

Spectroscopy has become a powerful tool for the determination of polymer structures. The major part of the book is devoted to techniques that are the most frequently used for analysis of rubbery materials, i.e., various methods of nuclear magnetic resonance (NMR) and optical spectroscopy. One chapter is devoted to (multi) hyphenated thermograviometric analysis (TGA) techniques, i.e., TGA combined with Fourier transform infrared spectroscopy (FT-IR), mass spectroscopy, gas chromatography, differential scanning calorimetry and differential thermal analysis. There are already many excellent textbooks on the basic principles of these methods. Therefore, the main objective of the present book is to discuss a wide range of applications of the spectroscopic techniques for the analysis of rubbery materials. The contents of this book are of interest to chemists, physicists, material scientists and technologists who seek a better understanding of rubbery materials. 

The microanalytical methods of differential thermal analysis, differential scanning calorimetry, accelerating rate calorimetry, and thermomechanical analysis provide important information about chemical kinetics and thermodynamics but do not provide information about large-scale effects. Although a number of techniques are available for kinetics and heat-of-reaction analysis, a major advantage to heat flow calorimetry is that it better simulates the effects of real process conditions, such as degree of mixing or heat transfer coefficients. 

An HDS additive, zinc/copper hydroxy stearate, was melt-blended with low density poly(ethylene). X-ray diffraction analysis of the composite materials was similar to that found with copper hydroxy dodecyl sulfate combined with poly(vinyl ester), where nanocomposite formation was observed, but additional work is necessary for full characterization of the dispersion. The (nano) composites were found to have better thermal stability via TGA and improvement in PHRR in cone calorimetry. However, smoke production was observed to increase. The 5% loading had better overall performance than 10% in terms of thermal stability and most fire properties.
