I am delighted to welcome you to Palavas from the 3rd to the 7th of June 2018 for the 17th IUPAC « Polymers and Organic Chemistry » international conference (POC 2018). This IUPAC conference is organized by research scientists of the Institute Charles Gerhardt of Montpellier (ICGM), with the support of National Center for Scientific Research (CNRS) and the National Graduate School of Chemistry of Montpellier (ENSCM). This conference will contribute to promote the role of polymers in various areas of chemistry (organic chemistry, chemical transformations, catalysis, polymer applications, and environmental issues), and will provide perfect opportunities for participants to present and share the results of their research in the fields of polymer chemistry and applications.The first POC conference took place in Lyon (France) in 1982. Since then, POC conference has been held every two years in different countries and continents (China, USA, Japan, Canada, Qatar, Romania). The latest POC conference was organized in Crete in 2016. In 2018, 36 years after the first edition, POC is back to France in the beautiful beach resort of Palavas.
