  • - Carry out enzymatic epoxidation of C22 fatty chains. - Optimize this synthesis (in-situ generation of peroxide, high yield, obtain pure products) - Generate the hydroxyl functions on the fatty acid - Synthesize hyperbranched polyesters from hydroxylated fatty chains - Analyze the molecular characteristics of polymers using standard characterization techniques (SEC, NMR, UV, IR, mass spectrometry) - Evaluate the physico-chemical properties of polymers (DSC, DMA, rheology, etc.) - Carry out the chemical modification of polymers to modify their solubility parameter - Establish the correlation between the structure and the properties of compounds - Write progress reports

    The role of the recruited agent will be to develop new biosourced hyperbranched polyesters. The work will include a section dedicated to the synthesis of these polymers by chemical and enzymatic catalysis as well as their post-functionalization. A second part will be dedicated to the characterization of the physico-chemical properties of these polymer materials and their evaluation for use in the fields of cosmetics and encapsulation.

    The project is a collaboration between the LCPO (Bordeaux), and the industrial technical center for fatty substances (ITERG). Most of the post- doc mission will take place at the LCPO in Bordeaux. The Organic Polymers Chemistry Laboratory (LCPO) is a joint research unit attached to the CNRS, the University of Bordeaux and Bordeaux INP Aquitaine. The LCPO is made up of 4 research teams and includes nearly 150 people, including around 50 permanent. With more than 30 years of experience in polymer chemistry polymers, LCPO research aims to: - develop innovative methodologies for the precision synthesis of polymers, using in particular biomimetic approaches and/or based on the principles of green chemistry - develop functional polymer materials by macromolecular engineering and self-assembly. The work of the recruited post-doc will be carried out within team 2 of the LCPO and in collaboration with ITERG.

    Team 2, entitled "Biopolymers and Bio-sourced Polymers", is led by Henri Cramail https:// www. lcpo.fr/team-2-biopolymers-bio-sourced-polymers/. The team develops the use of bio-resources for the synthesis of polymers with the following main orientations: - the use of vegetable oils (modified) as monomers - obtaining polymerizable building blocks from lignocellulosic biomass The work carried out during this contract will therefore be carried out in the context of team 2. It will be particularly important to take into consideration the "green" dimension of the syntheses developed (reduction of the number of steps, limitation of the use of toxic compounds ), and the use of biosourced compounds will be favoured. Supervision will be provided by Henri Cramail (Professor at the University of Bordeaux) and Etienne Grau (Lecturer at the University of Bordeaux and researcher at the LCPO). The work will be enhanced by patent filings and publications in journals with high impact factors.
