This report describes the theory of weathering and its effect on polymer properties, methods of stabilisation, and natural and accelerated weathering tests. The problems associated with particular polymers used in outdoor applications are explained. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database provides useful references for further reading.

This book presents newer applications of paramagnetic sensors for the study of polymer materials structure, microreology and molecular dynamics. Paramagnetic (or spin) sensors have found wide use in structural and dynamic research of condensed media using the spectroscopy of electron paramagnetic resonance (EPR). Stable nitroxide radicals are the most exploited paramagnetic sensors which formed the basis of spin probes and labels technique well known to the experts in fields of chemical and biological materials science. With the proliferation of new materials (composites, nano-dimensional fillers) new trends in the methodology of paramagnetic sensors application have been outlined. This book is devoted to these new trends in polymers and nanocomposites research. It observes the methods of adaptation of EPR spectroscopy of paramagnetic sensors to interface layers investigation, analysis of the systems containing magnetic nanoparticles, identification of composites ingredients by EPR spectra of free radicals, detection of the shear component of polymer materials deformation. This book also presents, at an accessible level, the theory of EPR, the structure and properties of paramagnetic sensors - stable nitroxide radicals and methods of basic parameters calculation from their EPR spectra. Intended for researchers and educators specialized in polymer material science and colloid chemistry. This book can also be used as a practical guide on paramagnetic resonance and paramagnetic sensors application for students and postgraduates.

The first international symposium on NDT-CE (Non-Destructive Testing in Civil Engineering) was held in Berlin, Germany in 1991. Successive symposia were held throughout Europe until 1997. This, the 5th symposium is organized as SEIKEN SYMPOSIUM No. 26, and is sponsored by the Institute of Industrial Science, at the University of Tokyo, Japan. Original objectives of the NDT-CE symposium have been to provide an opportunity for discussing current issues and future perspectives of NDT and for promoting mutual understanding among engineers and researchers. Asia is one of the key regions for further development in NDT and this symposium in Japan will be a good opportunity not only to exchange technical information on NDT, but to promote worldwide friendship between engineers in Asian countries and other nations of the world. This volume contains 70 papers providing the most recent research results and findings. The papers are grouped under the following areas: (1) keynote papers, (2) magnetic / electric, (3) steel structures, (4) integrated test, (5) moisture, (6) strength, (7) acoustic emission, (8) various tests, (9) ultrasonic, (10) impact echo, (11) radar, (12) quality and (13) corrosion / cover.
