After epoxy resins and polyimides, cyanate esters arguably form the most well-developed group of high-temperature, thermosetting polymers. They possess a number of desirable performance characteristics which make them of increasing technological importance, where their somewhat higher costs are acceptable. The principal end uses for cyanate esters are as matrix resins for printed wiring board laminates and structural composites. For the electronics markets, the low dielectric loss characteristics, dimen sional stability at molten solder temperatures and excellent adhesion to conductor metals at temperatures up to 250°C, are desirable. In their use in aerospace composites, unmodified cyanate esters offer twice the frac ture toughness of multifunctional epoxies, while achieving a service tem perature intermediate between epoxy and bis-maleimide capabilities. Applications in radome construction and aircraft with reduced radar signatures utilize the unusually low capacitance properties of cyanate esters and associated low dissipation factors. While a number of commercial cyanate ester monomers and prepoly mers are now available, to date there has been no comprehensive review of the chemistry and recent technological applications of this versatile family of resins. The aims of the present text are to present these in a com pact, readable form. The work is primarily aimed at materials scientists and polymer technologists involved in research and development in the chemical, electronics, aerospace and adhesives industries. It is hoped that advanced undergraduates and postgraduates in polymer chemistry and technology, and materials science/technology will find it a useful introduc tion and source of reference in the course of their studies.

The lives of three families; One Israeli, one Palestinian, and one German, are woven together.

In this “extraordinary family memoir,”* the National Book Award–winning author of The Future Is History reveals the story of her two grandmothers, who defied Fascism and Communism during a time when tyranny reigned. *The New York Times Book Review In the 1930s, as waves of war and persecution were crashing over Europe, two young Jewish women began separate journeys of survival. Ester Goldberg was a rebel from Bialystok, Poland, where virtually the entire Jewish community would be sent to Hitler’s concentration camps. Ruzya Solodovnik was a Russian-born intellectual who would become a high-level censor under Stalin’s regime. At war’s end, both women found themselves in Moscow. Over the years each woman had to find her way in a country that aimed to make every citizen a cog in the wheel of murder and repression. One became a hero in her children’s and grandchildren’s eyes; the other became a collaborator. With grace, candor, and meticulous research, Masha Gessen, one of the most trenchant observers of Russia and its history today, peels back the layers of time to reveal her grandmothers’ lives—and to show that neither story is quite what it seems. Praise for Masha Gessen “One of the most important activists and journalists Russia has known in a generation.”—David Remnick, The New Yorker “Masha Gessen is humbly erudite, deftly unconventional, and courageously honest.”—Timothy Snyder, author of On Tyranny

"In a counterfactual world resembling the 1930s, the state of Khazaria, an isolated nation of warriors Jews, is under attack by the Germanii. Esther, the precocious daughter of Khazaria's chief policy advisor, sets out on a quest to ensure the survival of her homeland"--

The idea of this book is to present the up-to-date research results on Nitrate Esters as explosive materials. It covers many aspects including the material structures, nitrating agent, chemical synthesis devices, preparation technology, and applications etc. In particular, this work sheds light on the comprehensive utilization and thorough destruction of the used Nitrate Easters which is crucial for preventing repeated pollution. This is a highly informative and instructive book providing insight for the researchers working on nitrating theory, energetic materials and chemical equipments.

This is the second volume in this series devoted to the solubility of esters with water. It includes solubility data for binary systems containing an ester and water up to the end of 1988. The critical evaluations were all prepared by one author and an introductory section has been included to elaborate the philosophy and methodology followed in the evaluations.
