Missions

The project's framework is a collaboration between CP2M laboratory and Solvay.
Polymers are omnipresent in modern life. Their recycling at the end of their life cycle is becoming a major challenge from an environmental and societal point of view. Reprocessing or mechanical recycling are potential solutions but the chemical valorization of end-life polymer products has emerged as a more attractive alternative and is expected to develop in the coming years. Indeed, it is in principle the ideal way of recycling since it consists in chemically decomposing macromolecules in order to obtain molecules of lower molar mass that could be reused as feedstock in a more sustainable circular economy loop.

In the present research project, two high performance specialty polymers of Solvay will be considered. The multidisciplinary project aims at developing innovative routes to depolymerize these polymers using innovative chemistry and in particular catalysis. The use of external mechanical forces (e.g. by ball milling) instead of thermal activation, that refers to mechanochemistry and/or mechanocatalysis, will be advantageously harnessed when required to activate strong covalent bonds and break-down polymer chains. Advanced characterizations of polymer and of depolymerization products (separation from GC or LC (/MS), structure/microstructure from IR/NMR, molar mass distribution from SEC, thermal properties from DSC…) will be important aspects of the project.

Activities

In the present research project, two high performance specialty polymers of Solvay will be considered. The multidisciplinary project aims at developing innovative routes to depolymerize these polymers using innovative chemistry and in particular catalysis. Therefore the activities will be divided into 3 main tasks:
- synthetic: chemical methodologies to be implemented to depolymerize native polymers and waster polymers back to monomers and useful plateform molecules
- advanced characterization: spectroscopic and physical (such as thermal analyses for instance) for both starting polymer "waste" and depolymerization products
- reporting and close collaboration with the CP2M research team as well as Solvay's research team

Skills

 Doctorate in polymer chemistry or organic chemistry
Strong knowledge of NMR is required, and knowledge of other spectroscopic methods would be considered an asset
 Knowledge of catalysis would be considered a strong asset

Recently the CP2M laboratory has been involved in several projects involving circular economy, through in particular the use of chemical recycling of polymers of both high tonnage and specialty to either go back to monomers or to useful platform molecules for the industry.
