This book is an up-to-date text on rubber science and is a breakthrough among many rubber-related publications. Emphasis is placed on the most modern scientific approaches to rubber science, departing from the usual detailed descriptions of trial-and-error results of traditional rubber technology. The book is a good introduction to modern rubber science both for graduate students and for more or less experienced rubber engineers for updating their way of thinking in handling of technological problems. Due to the increasing importance of pneumatic tires of vehicles and aircraft in modern transportation, this work will be of great use for general readers as well, including those who are concerned with sustainable development.

This sequel to A Prehistory of Polymer Science begins with the Faraday Discussion of 1935 on Polymerization. Patterson then examines the remarkable rise and establishment of polymer science after 1935 from the perspective of the emergence of strong intellectual leaders. While enough biographical detail is presented to gain an appreciation for the role played by each leader, the emphasis of this volume is on the key concepts associated with each individual and how the community embraced these leaders.

If, following the solvent extraction of a hydrocarbon from a plant, it is not known whether it is one or the other, a method of distinguishing the two is described by HENDRICKS, WILDMAN and JONES (1946). The technique involves the infra-red absorption spectra of the two isomers. At about 12 mp. the relative absorption coefficient of rubber is 42% greater than for gutta. ScHLESINGER and LEPER (1951) describe two procedures for separation of the rubber and gutta hydrocarbons from large quantities of crude chicle. In one, the chicle is extracted with benzene which dissolves both isomers. An excess absolute ethyl acetate is added and the mixture stored at 5° C overnight. The gutta precipitates out and the rubber remains in solution. The other method is as follows: (1) Ten grams of chicle are extracted with acetone for 24 hours in a Soxhlet extraction apparatus. (2) The insoluble material in the thimble is allowed to .. it dry, then immersed in 150 ml. of cold Skellysolve B in a refrigerator at 10° C and· allowed to stand for 48 hours with occasional agitation. (3) The thimble is then removed from the solvent and the enclosed residue washed several times with fresh, cold Skellysolve B. (4) An excess of acetone and a few drops of a concentrated aqueous solution of sodium iodide are added to the combined Skellysolve B extract and washings and allowed to stand overnight in a refrigerator.

Epoxy resins are polymers which are extensively used as coating materials due to their outstanding mechanical properties and good handling characteristics. A disadvantage results from their high cross-link density: they are brittle and have very low resistance to crack growth and propagation. This necessitates the toughening of the epoxy matrix without impairing its good thermomechanical properties. The final properties of the polymer depend on their structure. The book focuses on the microstructural aspects in the modification of epoxy resins with low molecular weight liquid rubbers, one of the prime toughening agents commonly employed. The book follows thoroughly the reactions of elastomer-modified epoxy resins from their liquid stage to the network formation. It gives an in-depth view into the cure reaction, phase separation and the simultaneous development of the morphology. Chapters on ageing, failure analysis and life cycle analysis round out the book.

Growing American Rubber explores America's quest during tense decades of the twentieth century to identify a viable source of domestic rubber. Straddling international revolutions and world wars, this unique and well-researched history chronicles efforts of leaders in business, science, and government to sever American dependence on foreign suppliers. Mark Finlay plots out intersecting networks of actors including Thomas Edison, Henry Ford, prominent botanists, interned Japanese Americans, Haitian peasants, and ordinary citizensùall of whom contributed to this search for economic self-sufficiency. Challenging once-familiar boundaries between agriculture and industry and field and laboratory, Finlay also identifies an era in which perceived boundaries between natural and synthetic came under review. Although synthetic rubber emerged from World War II as one solution, the issue of ever-diminishing natural resources and the question of how to meet twenty-first-century consumer, military, and business demands lingers today.

Through his voluminous and in?uential writings, editorial activities, organi- tional leadership, intellectual acumen, and strong sense of history, Clifford - brose Truesdell III (1919–2000) was the main architect for the renaissance of - tional continuum mechanics since the middle of the twentieth century. The present collection of 42 essays and research papers pays tribute to this man of mathematics, science, and natural philosophy as well as to his legacy. The ?rst ?ve essays by B. D. Coleman, E. Giusti, W. Noll, J. Serrin, and D. Speiser were texts of addresses given by their authors at the Meeting in memory of Clifford Truesdell, which was held in Pisa in November 2000. In these essays the reader will ?nd personal reminiscences of Clifford Truesdell the man and of some of his activities as scientist, author, editor, historian of exact sciences, and principal founding member of the Society for Natural Philosophy. The bulk of the collection comprises 37 research papers which bear witness to the Truesdellian legacy. These papers cover a wide range of topics; what ties them together is the rational spirit. Clifford Truesdell, in his address upon receipt of a Birkhoff Prize in 1978, put the essence of modern continuum mechanics succinctly as “conceptual analysis, analysis not in the sense of the technical term but in the root meaning: logical criticism, dissection, and creative scrutiny.

Unlike other treatments of sensors or actuators, this book approaches the devices from the point of view of the fundamental coupling mechanism between the electrical and mechanical behaviour. The principles of operation of the solenoid are the same in both cases, and this book thus treats them together. It begins with a discussion of systems analysis as a tool for modelling transducers, before turning to a detailed discussion of transduction mechanisms. The whole is rounded off by an input/output analysis of transducers.
