Photoinitiating systems for polymerization reactions are largely encountered in a variety of traditional and high-tech sectors, such as radiation curing, (laser) imaging, (micro)electronics, optics, and medicine. This book extensively covers radical and nonradical photoinitiating systems and is divided into four parts: * Basic principles in photopolymerization reactions * Radical photoinitiating systems * Nonradical photoinitiating systems * Reactivity of the photoinitiating system The four parts present the basic concepts of photopolymerization reactions, review all of the available photoinitiating systems and deliver a thorough description of the encountered mechanisms. A large amount of experimental and theoretical data has been collected herein. This book allows the reader to gain a clear understanding by providing a general discussion of the photochemistry and chemistry involved. The most recent and exciting developments, as well as the promising prospects for new applications, are outlined.

The art and science of macromolecular architecture is based on synthesis, analysis, processing, and evaluation of physical properties of polymers. The growing specificity of available synthetic methods and the increasing refinement of analytical and physical analysis are gradually providing a deeper insight into structure-property relationships of polymers, upon which many applications can be based. This book deals with recent methods for polymer synthesis. Those that lead to specific structures have been selected especially. Background, mechanism scope and limitations, and illustrative procedures are given for each method. With this layout the editor hopes that the book will provide a practical guideline, for the synthetic polymer chemist in industry or at a university graduate school, on how to apply the methods in the design of new polymer structures. The editor is grateful to the authors not only for their contributions containing interesting new developments in polymer synthesis, but also for the way they have fitted their text into the general framework of the book. The elegant chemistry described in the following chapters will, it is hoped, inspire more organic chemists to apply their skills to polymer synthesis, where the beauty of organic chemistry in terms of structural control and reactivity may be even more apparent than in the low molecular field.

This book is a collection of selected papers presented at the symposium titled "In situ Spectroscopy in Monomer and Polymer Synthesis," held at the April, 2001 ACS National Meeting in San Diego, California, USA. The co-organizers of this symposium were Timothy Long, Judit E. Puskas, Robson F. Storey, and J. Andrews. In situ spectroscopic monitoring is gaining popularity both in academia and industry. FfIR monitoring is used most frequently, but UV-visible, raman, and NMR spectroscopy are also important. This book concentrates mostly on FfIR monitoring, both in the near and mid-infrared ranges. The first chapter is a short general overview of FfIR spectroscopy, followed by the symposium contribu tions. We thought that this would be especially useful for student readers. We hope that the book will present a state-of-the-art overview of research related to in situ spectroscopic monitoring. -Judit E. Puskas ix Acknowledgments This book would not have been possible without the dedicated effort of the chapter contributors and the symposium committee: Professor Judit E. Puskas Professor Timothy Long Professor Robson F. Storey Professor J. Andrews The symposium was financially supported by: ACS-Petroleum Research Fund REMSPEC Co. Wyatt Technology Co.

3D printing is forecast to revolutionise the pharmaceutical sector, changing the face of medicine development, manufacture and use. Potential applications range from pre-clinical drug development and dosage form design through to the fabrication of functionalised implants and regenerative medicine. Within clinical pharmacy practice, printing technologies may finally lead to the concept of personalised medicines becoming a reality. This volume aims to be the definitive resource for anyone thinking of developing or using 3D printing technologies in the pharmaceutical sector, with a strong focus on the translation of printing technologies to a clinical setting. This text brings together leading experts to provide extensive information on an array of 3D printing techniques, reviewing the current printing technologies in the pharmaceutical manufacturing supply chain, in particular, highlighting the state-of-the-art applications in medicine and discussing modern drug product manufacture from a regulatory perspective. This book is a highly valuable resource for a range of demographics, including academic researchers and the pharmaceutical industry, providing a comprehensive inventory detailing the current and future applications of 3D printing in pharmaceuticals.
