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.

This peculiar property, not observed for linear pseudopolyrotaxanes, allows the processing of star-pPRs while preserving their supramolecular assembly. Thus, original PCL:star-pPR core:shell nanofibers are elaborated by coaxial electrospinning. The star-pPR shell ensures the presence of available CD hydroxyl functions on the fiber surface allowing its postfunctionalization. As proof of concept, fluorescein isothiocyanate is grafted. Moreover, the morphology of the fibers is maintained due to the star-pPR shell that acts as a shield, preventing the fiber dissolution during chemical modification. The proposed strategy is simple and avoids the synthesis of polyrotaxanes, i.e., pPR end-capping to prevent the CD dethreading. As PCL is widely us...

Free form of Candida antarctica lipase B (CALB) and its clay- and acrylic resin- immobilized forms were compared. For L- and D,L-lactide monomers only short oligomers were obtained. The acrylic resin immobilized form of CALB (NOVO-435) led to a complete conversion of D-lactide to PDLA with a Mn of 2|600 g/mol, whereas the clay-immobilized and free forms of CALB exhibited slower kinetics and produced chains of lower Mn. Copolymerization reactions between ɛ-caprolactone and lactide isomers were performed using NOVO-435 as bio-catalyst. Random copolyesters were successfully synthesized by copolymerizing D-lactide with ɛ-caprolactone. Better results were obtained with a two-step reaction, starting from presynthesized polycaprolactone chains, compared with the one-pot copolymerization. Conducting this two-step copolymerization in the presence of organo-modified montmorillonite allowed the successful synthesis of copolymer/clay nanohybrids.
