Book Description
Carborane substituted polyphosphazenes were prepared by the thermal polymerization of phenyl-carboranyl penta chlorocyclotriphosphazene. Successive isothermal vacuum pyrolyses were conducted on the polymer and examined for structural changes by infrared spectroscopy. The degradation products were ascertained by gas chromatography-mass spectrometric analysis. It was found that the presence of the carborane group improves the thermal stability of the polymer by retarding the ring chain equilibrium processes of decomposition. Fewell, L. L. and Basi, R.

Book Description
A compact but comprehensive review of the most important preparative methods for the synthesis and chemical modification of polymers. The contents of the two-volume handbook (Part A was cited in the May 1992 SciTech Book News) are subdivided according to the chemical structure of the polymer backbone on the one hand (Chapters 1-14 of Part A and 15-18 of Part B) and special properties and applications of polymers regardless of their chemical structure on the other hand (Chapters 19-27 of Part B). The latter chapters deal with, for instance, electroconductive polymers, polymeric reagents, and models of bio-polymers. Includes some 11,000 references to the original literature.

Book Description
Carboranes, Second Edition is designed as a comprehensive source of information in a field that has experienced enormous growth in both its fundamental and applied aspects in the four decades since the publication of Carboranes (1970). During this long period thousands of original research papers have appeared, along with many review articles and book chapters dealing with aspects of carborane chemistry. As carborane science has grown in complexity, and applications have advanced steadily in areas such as medicine, nanostructured and electroactive materials, catalysis, polymers, and others, the need for a monograph covering the entire area in a unified treatment has become increasingly apparent. This volume has two principal objectives, the first of which is to provide a readable and concise introduction to the basic principles underlying the synthesis, structures, reactivity, and applications of carboranes and metallacarboranes at a level suitable for readers in industry and academe who are not trained in boron chemistry but find themselves working with, or lecturing about carboranes. Secondly, the book furnishes a trove of detailed information for workers active in carborane science and associated technologies. To that end, it incorporates tables listing thousands of specific compounds keyed to literature references, together with more than 2,000 molecular structure drawings that illuminate the accompanying discussion. Thorough treatment of the synthesis, structures, and reactions of carboranes, heterocarboranes, and metallacarboranes in the first 13 chapters is followed by four chapters detailing advances in practical applications in polymer science, catalysis, medicine, and other areas. Includes over 2,000 molecular structure drawings throughout the text Features tables listing thousands of compounds with key literature references
