This book contains contributions of the 7th Dresden Polymer Discussion held in Mei?en near Dresden from April 19 to 22, 1999. The conference was dedicated to the field 'Characterization of polymer sorption phenomena: From solution to the surface'. Research in the area of modification and characterization of surfaces and interfaces of solids has been booming in the last few years, due to its enormous importance and potential for the development of novel technologies in materials research and engineering. Therefore the 7th Dresden Polymer Discussion, held from April 19 to 22, 1999, was dedicated to the field 'Characterization of polymer sorption phenomena: from solution to the surface'. The publication of the proceedings in this book may contribute to further progress in this field.
