This Volume 5 in a continuing series represents the compilation of papers presented at the International Symposium on Analytical Calorimetry as part of the 185th National Meeting of the American Chemical Society, Seattle, Washington, March 20-25th. 1983. A much broader variety of topics are covered than in pre­ vious volumes, due to the growth in the field of Thermal Analysis. Specific topics covering such techniques as differential scanning calorimetry, combined thermogravimetric procedures, dynamic mechan­ ical analysis and a variety of novel kinetic analyses are covered. A wide range of material types are included in this volume such as polymers (alloys, blends and composites), fossil fuels, biological
