As a chairman , I would like to send a cordial and warm invitation to participate in the forthcoming 8-TH INTERNATIONAL SYMPOSIUM “MOLECULAR ORDER AND MOBILITY IN POLYMER SYSTEMS’’ which will be held in St.Petersburg, Russia, 2-6 of June, 2014. The Symposium is under the sponsorship of IUPAC. The Symposium is one of the most important international polymer meetings in Russia. It continues a serie of Symposia organized by the Institute of Macromolecular Compounds of Russian Academy of Sciences and titled alternatively as “Molecular Mobility and Order in Polymer Systems”(I- 1994, III-1999, V- 2005, VII - 2011) and “Molecular Order and Mobility in Polymer Systems”.(II- 1996, IV-2002, VI- 2008). The main aim of the Symposium is to discuss modern problems of physics and chemistry of complex stimuli-responsive polymer systems with nano-structure organization and "soft" order preserving a pronounced molecular mobility. Both experimental data and results of theory and simulation will be presented. The Symposium program will include about 20 plenary lectures, oral presentations and poster sections. Within the symposium a joint summer school on “Theory and modeling of solutions of branched ionic macromoles” will be organized as a part of the EC FP-7 International Staff Exchange Scheme (contract agreement with EC PIRSES-GA-2013-612562, POLION) “Mesoscopic modeling of synthetic and biological ionic macromolecular systems” The Symposium is placed in the historical centre of the city in the Palace of Scientists. Our guests can combine the participation in meeting sessions and the visiting the well recognized historical sites of one of the most beautiful cities of the world.
