Issue Date: | 2020 | Publisher: | ROYAL SOC CHEMISTRY | Source: | Polymer chemistry, 11 (21) , p. 3546 -3550 | Abstract: | High-resolution FlowNMR was coupled to a continuous flow reactor to monitor polymer molecular weight evolution online by diffusion ordered NMR spectroscopy. Polymers were synthesized by reversible addition fragmentation chain transfer polymerization in continuous flow. The setup allows to target various polymer chain lengths in a dynamic manner without requiring additional purification or sample preparation. Obtaining molecular weight information in this manner is shown to be more accurate than classical SEC analysis at comparable measurement times, with relative errors around 5%. | Notes: | Junkers, T (corresponding author), Hasselt Univ, Martelarenlaan 42, B-3500 Hasselt, Belgium.; Junkers, T (corresponding author), Monash Univ, Sch Chem, Polymer React Design Grp, 19 Rainforest Walk,Bldg 23, Clayton, Vic 3800, Australia.; Hintermair, U (corresponding author), Univ Bath, Ctr Sustainable & Circular Technol, Bath BA2 7AY, Avon, England.; Hintermair, U (corresponding author), Univ Bath, Dynam React Monitoring Facil, Bath BA2 7AY, Avon, England. u.hintermair@bath.ac.uk; tanja.junkers@monash.edu |
