Résumé
Polymer materials and sustainable development The second half of the 20(th) century, sometimes called "the plastic age", knew a boom of polymer materials in all the sectors of industrial activity. Nowadays, although polymer production is continuously growing, all the developed countries are facing new challenges regarding the rarefaction of fossil resources and the sustainable development. Many research works performed in the institutions affiliated to the "Federation Gay-Lussac" aim to contribute to this field by exploring some new aspects of polymer science. They include: unusual polymerization reactions, new types of tri-dimensional networks, valorization of natural polymers, biocomposites and nano-biocomposites, durability of polymeric products.
