SEC NMR
Molecular structure of polymers revealed by size exclusion chromatography (SEC) coupled to benchtop nuclear magnetic resonance (NMR) spectroscopy for the valorisation of biobased polymers and polymers in wastes
Natural resources, such as petrol, are running low while wastes such as plastic ones have a strong impact on the environement. The move to a circular economy relies on the combination of approaches including biosourcing polymers from biomass, reuse, upcycling and recycling. Current oil-based polymers are characterized through their size determined by chromatography (SEC) and their average composition by nuclear magnetic resonance (NMR). Polymers in a circular economy are more diverse and complex due to the high diversity of chemistry in the biomass than in oil or the evolution of polymers during recycling. To reveal this new complexity and turn it into an advantage, more advanced characterization methods are needed: a new instrument coupling chromatography to NMR online, not present in Ile-de-France so far, is proposed to enable the development of biosourcing and recycling.
