Take an in-depth look at the modern problems of the equilibrium state in polymer science. The lectures published in this book reflect the progress of the investigators' interests towards more complicated systems with the elements of nanostructure organization. Topics include Copolymers and Polymer Blends, Macromolecules in Solution, Polymer Brushes, Micelles and Complexes,Polymer Networks, Bulk Polymers, and LC Polymer Systems. The Fourth International Symposium "Molecular Order and Mobility in Polymer Systems" held in June 2002 continued the series of St.-Petersburg IUPAC meetings organized by the institute of Macromolecular Compounds of the Russian Academy of Scientists (RAS).
