Book Description
Gleria (materials science, Padova University, Italy) and De Jaeger (chemistry, University of Sciences and Technologies, France) present the latest work in the synthesis and characterization of poly(organophosphazenes). The book opens with a general introduction on background, developments, and future perspectives, then covers the synthetic aspects of phosphazene polymers, with chapters on areas such as ambient temperature cationic condensation synthesis of polyphosphazenes and high molecular weight polyspirophosphazenes. Chapters on the characterization of phosphazene polymers in solution explore topics including thermal and mechanical properties of polyphosphazenes and electrochemical behavior of phosphazenes.

Book Description
The main aim of this book is to provide a complete picture of current research on phosphazene compounds carried out around the world. The book opens with a general introduction, then moves on to cover synthetic aspects of phosphazene polymers, their characterization in solution and from the theoretical, thermal, and mechanical points of view; application aspects of poly(organophosphazenes); and the synthesis, characterization, and practical utilization of cyclophosphazenes. There is particular focus on the use of cyclophosphazenes as hydraulic fluids and additives, as cores for star polymers or dendrimers, and as starting substrates for supramolecular chemistry and nanostructured materials. The spectroscopic characterization of these compounds by NMR and Raman techniques is also discussed. Annotation : 2004 Book News, Inc., Portland, OR (booknews.com).

Book Description
Polymers continue to play an ever increasing role in the modern world. In fact it is quite inconceivable to most people that we could ever have existed of the increased volume and variety of materials without them. As a result currently available, and the diversity of their application, characterisation has become an essential requirement of industrial and academic laboratories in volved with polymeric materials. On the one hand requirements may come from polymer specialists involved in the design and synthesis of new materials who require a detailed understanding of the relationship between the precise molecular architecture and the properties of the polymer in order to improve its capabilities and range of applications. On the other hand, many analysts who are not polymer specialists are faced with the problems of analysing and testing a wide range of polymeric materials for quality control or material specification purposes. We hope this book will be a useful reference for all scientists and techno or industrial laboratories, logists involved with polymers, whether in academic and irrespective of their scientific discipline. We have attempted to include in one volume all of the most important techniques. Obviously it is not possible to do this in any great depth but we have encouraged the use of specific examples to illustrate the range of possibilities. In addition numerous references are given to more detailed texts on specific subjects, to direct the reader where appropriate. The book is divided into II chapters.

Book Description
Phosphorus-Nitrogen Compounds: Cyclic, Linear, and High Polymeric Systems concerns itself with the chemistry of compounds containing alternating phosphorus - nitrogen atoms in the skeleton. The monograph aims to be an introduction to phosphorus-nitrogen chemistry, a review of advances in the field, and reference work. The text is divided into three parts. Part I covers the introduction, historical background, and nomenclature of phosphorus-nitrogen compounds and the theories in bonding and structure of phosphazenes and phosphazanes. Part II deals with reactions such as the synthesis of the phosphorus-nitrogen skeleton, hydrolysis of phosphazenes and phosphazanes, and the aminolysis of halophosphazenes. Part III discusses polymer chemistry and includes topics such as polymerization, depolymerization, and phosphazene polymers. The book is recommended for students and practitioners in the field of chemistry, especially those concerned with phosphorus nitrogen compounds and polymeric systems.

Book Description
Brings together, analyzes, and contextualizes the latest findings and practical applications Polyphosphazenes, an emerging class of polymers, include macromolecules, which have been proven to be biocompatible, biodegradable, and bioactive. Their unprecedented structural diversity and unique properties make them suitable as vaccine adjuvants, microencapsulating agents, biodegradable materials, scaffolds for tissue engineering, biocompatible coatings, and carriers for gene delivery. Polyphosphazenes for Biomedical Applications offers a thorough review of polyphosphazene research findings in the life sciences, chemistry, and chemical engineering. It emphasizes biomedical applications as well as recent advances in polyphosphazene development such as high-throughput discovery and the latest controlled methods of synthesis. The book brings together, analyzes, and contextualizes a wealth of knowledge that previously could only be found scattered throughout the scientific literature. Following two introductory chapters, the book reviews: Vaccine delivery and immunomodulation Biomaterials Drug delivery systems Biodetection Well-defined polyphosphazenes: synthetic aspects and novel molecular architectures All the chapters have been written by leading researchers in the field. Editor Alexander Andrianov, who has led the effort to commercialize polyphosphazenes for biomedical applications, has carefully reviewed and edited all chapters to ensure readability, accuracy, and thoroughness. Polyphosphazenes for Biomedical Applications is not only intended for researchers working in polyphosphazene chemistry, but also for all researchers seeking solutions to problems arising in the areas of biomaterials, drug delivery systems, and controlled release formulations.

Book Description
This volume serves as a valuable handbook for the development of nanomedicines made of polymer nanoparticles because it provides researchers, students, and entrepreneurs with all the material necessary to begin their own projects in this field. Readers will find protocols to prepare polymer nanoparticles using different methods, since these are based on the variety of experiences that experts encounter in the field. In addition, complex topics such as, the optimal characterization of polymer nanoparticles is discussed, as well as practical guidelines on how to formulate polymer nanoparticles into nanomedicines, and how to modify the properties of nanoparticles to give them the different functionalities required to become an efficient nanomedicine for different clinical applications. The book also discusses the translation of technology from research to practice, considering aspects related to industrialization of preparation and aspects of regulatory and clinical development.
