The aim is to improve your knowledge in classical macromolecular engineering by presenting the recent trends to develop highly functional polymer materials with dedicated properties. It aims at completing the basic knowledge in macromolecular chemistry and at understanding with a critical view the recent evolutions and most efficient tools recently developed to afford complex tailored macromolecules for dedicated applications. The program will involve four different sections: 1 - A critical reminder of the general concepts involved in controlled/living polymerization approaches 2 - The introduction to reversible deactivation radical polymerization techniques mediated by light 3 - The historical introduction of the Click chemistry paradigm and its application to macromolecular engineering 4 - The application of photo-Click chemistry to macromolecular engineering
