Opis

Thermal analysis cuts a broad swath through contemporary science. Within this domain, advances in instrumentation permit the application of quantitative calorimetry to the full spectrum of modern materials. This can be illustrated perhaps no better than by the set of contributions which make up this Volume II of Analytical Calorimetry. Comprehensive studies are included on an array of polymers, copolymers, and polyblends. Calorimetry is also reported on biopolymers, gels, liquid crystals, alloys, and on a variety of inorganic compounds and materials including moon rocks. Applica- tions of calorimetric techniques to chemical reaction are also detailed. These include t e study of decompositions, catalytic reductions, kinetics of dissolution, and the measurement of poly- merization heats as well as the curing of thermosetting resins. The techniques employed are principally differential thermal analysis and differential scanning calorimetry. Several contribu- tors have also illustrated the application of important and related techniques such as thermogravimetry, thermal depolarization analysis, and thermetric titrations. The contributions to this volume represent papers presented before the American Chemical Society Symposium held in Chicago, September 14 and 15, 1970. This symposium 0n Analytical Calori- metry was sponsored by the Division of Analytical Chemistry.
