Opis: Polymer Thermodynamics - Kal Renganathan Sharma, K Sharma

Polymer Thermodynamics: Blends, Copolymers and Reversible Polymerization describes the thermodynamic basis for miscibility as well as the mathematical models used to predict the compositional window of miscibility and construct temperature versus volume-fraction phase diagrams. The book covers the binary interaction model, the solubility parameter approach, and the entropic difference model. Using equation of state (EOS) theories, thermodynamic models, and information from physical properties, it illustrates the construction of phase envelopes. The book presents nine EOS theories, including some that take into account molecular weight effects. Characteristic values are given in tables. It uses the binary interaction model to predict the compositional window of miscibility for copolymer/homopolymer blends and blends of copolymers and terpolymers with common monomers. It discusses Hansen fractional solubility parameter values, six phase diagram types, the role of polymer architecture in phase behavior, and the mathematical framework for multiple glass transition temperatures found in partially miscible polymer blends. The author also illustrates biomedical and commercial applications of nanocomposites, the properties of various polymer alloys, Fick's laws of diffusion and their implications during transient events, and the use of the dynamic programming method in the sequence alignment of DNA and proteins. The final chapter reviews the thermodynamics of reversible polymerization and copolymerization. Polymer blends offer improved performance/cost ratios and the flexibility to tailor products to suit customers' needs. Exploring physical phenomena, such as phase separation, this book provides readers with methods to design polymer blends and predict the phase behavior of binary polymer blends using desktop computers. The morphology of materials is a fascinating field and structure-related properties are of key interest in product development and process engineering, resulting in materials with advanced performance in sustainable, environmentally friendly applications. ... This text is a welcome and highly effective response to this challenge that must be met if we are to develop the sustainable technologies we shall certainly need to survive into the next century. -From the Foreword by Harold Kroto, Department of Chemistry and Biochemistry, Florida State University, Tallahassee, USAIntroduction to Polymer Blends History of Polymer Blends Flory-Huggin's Solution Theory-and Beyond Miscible Polymer Blends Partially Miscible Polymer Blends Natural Polymers Polymer Alloy Equation of State Theories for Polymers Small Molecules and Large Molecules PVT Relations for Polymeric Liquids Tait Equation Flory, Orwoll, and Vrij Model Prigogine Square-Well Cell Model Lattice Fluid Model of Sanchez and Lacombe Negative Coefficient of Thermal Expansion Binary Interaction Model Introduction Compositional Window of Miscibility: Copolymer-Homopolymer Compositional Window of Miscibility: Copolymers with Common Monomers Compositional Window of Miscibility: Terpolymer System with Common Monomers Compositional Window of Miscibility: Terpolymer and Homopolymer System without Common Monomers Spinodal Curve from B Values and EOS Copolymer/Homopolymer Blends of AMS-AN/PVC Copolymer/Homopolymer Blends of AMS-AN with Other Copolymers Intramolecular Repulsion as Driving Force for Miscibility-Mean Field Approach Keesom Forces and Group Solubility Parameter Approach Hildebrandt Solubility Parameter Hansen Three-Dimensional Solubility Parameter Specific Interactions Phase Behavior Introduction LCST and UCST Circular Envelope in Phase Diagram Hourglass Behavior in Phase Diagrams Molecular Architecture Partially Miscible Blends Commercial Blends That Are Partially Miscible Entropy Difference Model (I"I"Sm) Estimates of Change in Entropy of Mixing at Glass Transition, I"I"Sm Copolymer and Homopolymer Blend Sequence Distribution Effects on Miscibility Polymer Nanocomposites Introduction Commercial Products Thermodynamic Stability Vision and Realities Fullerenes Carbon Nanotubes (CNT) Morphology of CNTs Nanostructuring Operations Polymer Thin Films Nanostructuring from Self-Assembly of Block Copolymers Intercalated and Exfoliated Nanocomposites Polymer Alloys Introduction PC/ABS Alloys Nylon/ABS Alloys PVC Alloys Polyolefin Alloys Natural Polymer Alloy Binary Diffusion in Polymer Blends Introduction Diffusion Phenomena Fick's First and Second Laws of Diffusion Skylab Diffusion Demonstration Experiments Bulk Motion, Molecular Motion, and Total Molar Flux Stokes-Einstein Equation for Dilute Solutions Diffusion in Solids Diffusion Coefficient in Polymers Transient Diffusion Damped Wave Diffusion and Relaxation Periodic Boundary Condition Copolymer Composition Introduction Composition for Random Copolymers Composition of Random Terpolymers Reactivity Ratios Multicomponent Copolymerization-n Monomers Sequence Distribution of Copolymers Dyad and Triad Probabilities in Copolymer Dyad and Triad Probabilities in Terpolymers Sequence Alignment in DNA and Protein Sequences Reversible Polymerization Heat Effects during Polymerization Ceiling Temperature during Reversible Polymerization Subcritical Oscillations during Thermal Polymerization Thermal Terpolymerization of Alphamethyl Styrene, Acrylonitrile, and Styrene Reversible Copolymerization Appendix A: Maxwell's Relations Appendix B: Five Laws of Thermodynamics Appendix C: Glass Transition Temperature Appendix D: Statistical Distributions Index A Summary and References appear at the end of each chapter.
