This third volume completes the first part of the project " Macromolecular Physics." The first volume dealt with the description of macromolecular crystals; the second volume dealt with crystal growth; and the third volume summarizes our knowledge of the melting of linear, flexible macromolecules. The discussion in the three volumes goes from reasonably well-established topics, such as the structure, morphology, and defects in crystals, to topics still in flux, such as crystal nucleation, detailed growth mechanisms, and annealing processes, to arrive at the present topics of equilibrium, nonequilibrium, and copolymer melting. Our knowledge is quite limited on many aspects of these latter topics.

Thermal Analysis deals with the theories of thermal analysis (thermodynamics, irreversible thermodynamics, and kinetics) as well as instrumentation and techniques (thermometry, differential thermal analysis, calorimetry, thermomechanical analysis and dilatometry, and thermogravimetry). Applications of thermal analysis are also described. This book consists of seven chapters and begins with a brief outline of the history and meaning of heat and temperature before listing the techniques of thermal analysis. The reader is then introduced to the basis of thermal analysis, paying particular attention to the macroscopic theories of matter, namely, equilibrium thermodynamics, irreversible thermodynamics, and kinetics. The next chapter discusses thermometry, focusing on the international temperature scale and the techniques of measuring temperature. Examples of heating and cooling curves are linked to the discussion of transitions. The groundwork for a detailed understanding of transition temperature is given. The chapters that follow explore the principles of differential thermal analysis, calorimetry, thermomechanical analysis and dilatometry, and thermogravimetry. This book is intended for the senior undergraduate or beginning graduate student, as well as for the researcher and teacher interested in thermal analysis.

Macromolecular Physics, Volume 1: Crystal Structure, Morphology, Defects provides a unified treatment of crystals of linear macromolecules. This book is organized into four chapters: structure of macromolecules, microscopic structure of crystals, crystal morphology, and defect crystal. This publication specifically discusses the macromolecular hypothesis, molecular conformation, and synthesis of macromolecules. The discovery and proof of the lattice theory, structures of minimum free energy, and crystal structures of macromolecules are also deliberated. This publication likewise covers the macromolecular crystals, macroscopic recognition of defects, and deformation of polymer crystals. This volume is a good reference for physicists, scientists, and specialists concerned with research on crystals of linear macromolecules.

Macromolecular Physics, Volume 2: Crystal Nucleation, Growth, Annealing continues the discussion of crystals of linear macromolecules. The text also gives conclusion about the description and formation of crystals. The book covers topics such as the primary, secondary, and tertiary nucleation of crystals; the general growth of crystals; solution and melt crystallization of macromolecules; and the general annealing of crystals. For those who wish to do further reading, the table of contents of Volume 1 is included in the book. The text is recommended for macromolecular physicists, especially those whose focus is on the study of crystals and its different properties.

Thermal analysis is an old technique. It has been neglected to some degree because developments of convenient methods of measurement have been slow and teaching of the understanding of the basics of thermal analysis is often wanting. Flexible, linear macromolecules, also not as accurately simply called polymers, make up the final, third, class of molecules which only was identified in 1920. Polymers have neverbeenfullyintegratedintothedisciplinesofscienceandengineering. Thisbook is designed to teach thermal analysis and the understanding of all materials, flexible macromolecules, as well as those of the small molecules and rigid macromolecules. The macroscopic tool of inquiry is thermal analysis, and the results are linked to microscopic molecular structure and motion. Measurements of heat and mass are the two roots of quantitative science. The macroscopic heat is connected to the microscopic atomic motion, while the macroscopic mass is linked to the microscopic atomic structure. The macroscopic unitsofmeasurementofheatandmassarethejouleandthegram,chosentobeeasily discernable by the human senses. The microscopic units of motion and structure are 12 10 the picosecond (10 seconds) and the ångstrom (10 meters), chosen to fit the atomic scales. One notes a factor of 10,000 between the two atomic units when expressed in “human” units, second and gram—with one gram being equal to one cubic centimeter when considering water. Perhaps this is the reason for the much better understanding and greater interest in the structure of materials, being closer to human experience when compared to molecular motion.

Today is Sunday, June 17, 2007. Father’s Day. Naturally, the obligatory, carefully selected cards, phone calls, and small gifts arrived from the children and grandchildren. Best wishes for Father’s Day were also the first words in the morning from Heidel, my wife of 54 years, although for many years I had made the comment: “I am not your father. ” But, in the frame of my life’s experiences th th in the 20 century, as I intend to summarize them over the next few years, the 17 of June has much deeper significance. This was the day in 1953 when we finally fled from our life of oppression which had lasted 20 years. Two successive dictatorships, one of Hitler and the other of Stalin, caused the most horrific slaughter of civilians and soldiers, eclipsing all prior history. During these first years of my life, I was plainly lucky to survive. After this day, I had a much better chance to experience the freedom needed to lead a life of creativity, satisfaction, and ultimately prosperity, all directed largely by our own decisions. th The 17 of June 1953 was a Wednesday. I stayed in the apartment of my parents in my hometown of Brandenburg, in the German Democratic Republic (GDR), the former Russian occupied zone of Germany.
