Download or read book Chemistry and Technology of Cyanate Ester Resins written by I. Hamerton and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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
Download or read book Aunt Ester s Children Redeemed written by Riley K. Temple and published by Wipf and Stock Publishers. This book was released on 2017-02-13 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: August Wilson (1945-2005) wrote one play for every decade of the twentieth century that explored black life in America for the descendants of slaves. All of his characters seek wholeness, identity, and reconstituted selves after the terror of 250 years chattel slavery and its terrifying legacy. Their history, culture, wisdom, joys, triumphs, pain, sufferings, victories, weaknesses, and strengths are all embodied in one character, Aunt Ester. She is as old as the number of years blacks have been on these shores. All of the characters in the ten-play cycle are her children. Their search is through circumstance and adventure, certainly. This author demonstrates how Wilson uses language--poetry, the blues--to bring each play's characters to a point of wholeness, redemption, and freedom, not from history, but ennobled and strengthened by it. Wilson employs fundamental theological doctrines to exhort Aunt Ester's children to remember by whom and how they were freed and made whole.

Download or read book Transformations of Allyl Substituted and Aryl Allyl Esters and Their Corresponding Amines written by Levashova and published by CRC Press. This book was released on 2005-06-14 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book generally shows the interrelation between allyl unit structure of the initial ester and composition and structure of its products. The first part studies the pathways of chemical regrouping in chlorallylaryl and bisarylallyl esters using quantum-chemical calculations. Energy parameters, structural features and electron structure of intermediates and transition states are also discussed. Simple and regioselective methods for compound synthesis inaccessible in other production techniques are developed. For the first time, new four- and eight-term nitrogen-containing heterocyclic compounds were produced by aniline alkenylation technique. In 0.05% aqueous solution these compounds displayed 100% activity in suppression of sulfate-reducing bacterium growth. Two new classes of complex action preparations designed for the oil production rate increase were obtained by heterocyclic amine alkenylation. Production methods for N-alkenyl ammonium salts derived from hexamethylene tetramine are developed and introduced into production, and compounds are used on oil fields. In the second part production methods of new mono-, di-, tri- and tetra-tert-butyl hexamethylene tetramine chlorides are discussed. These compounds fully suppress sulfate-reducing bacterium growth already in 200 – 500 mg/l concentration. A universal technology deriving bactericides and sulfide corrosion inhibitors for metals from methallyl chloride is developed. It also gives a method for organochlorine waste and methallyl chloride production wastewater management, safe for the environment.

Download or read book The Determination of Esterified Fatty Acids in Glycerides Cholesterol Esters and Phosphatides written by W. D. Skidmore and published by . This book was released on 1962 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hydroxamic acid reaction conditions for the determination of esterified fatty acids were modified to the extent that the variable factors involved were controlled so that the molar absorptivities per ester group for triglycerides, cholesteryl esters of long-chain fatty acids, and phosphatides were equivalent through 8 microequivalent ester. The amount of water present during the formation of hydroxamates was the most important single factor in obtaining equivalent color values with these 3 types of esters. The accuracy and precision of the method were well defined by showing that the optical density values for 5 different ester standards were on the identical straight line curve. Spectral curves between the wavelengths of 410 and 700 millimicron with standard carboxylic acid esters and Folch extracts of rat serum, rat liver, and human serum were qualitatively and quantitatively identical. A long chain cholesteryl ester must be used as one of the standard esters because of its solubility characteristics and water sensitivity. Cholesteryl acetate can not be used as a reliable representative in place of a long chain cholesteryl ester. (Author).
