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.

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.

Carboranes, Third Edition, by Russell Grimes, is the definitive resource on the subject. Completely updated with a wealth of research and review articles published in this active field since the previous volume was released in 2011, the book provides a readable and concise introduction to the basic principles underlying the synthesis, structures, and reactions of carboranes, heterocarboranes, and metallacarboranes. Following the valuable foundational information, the book explores the advances in practical applications for the many areas in which experts have discovered that carboranes afford new possibilities for solving problems and advancing the science. These disciplines include polymer science, catalysis, biomedicine, nanomaterials, and others. - Winner of a 2017 Textbook Excellence Award (Texty) from the Textbook and Academic Authors Association - Includes over 2,000 molecular structure drawings throughout the text - Features expanded coverage on applications of carboranes, particularly in biomedicine and nanomaterials, given the growth of research in these areas - Presents extended and updated tables, listing thousands of compounds with key literature references, provided online via the book's website - Explores the advances in practical applications for the many areas in which experts have discovered that carboranes afford new possibilities for solving problems and advancing the science
