摘要: High-resolution FlowNMR was coupled to a continuous flow reactor monitor polymer molecular weight evolution online by diffusion ordered NMR spectroscopy. Polymers were synthesized reversible addition fragmentation chain transfer polymerization in flow. The setup allows target various lengths dynamic manner without requiring additional purification or sample preparation. Obtaining information this is shown be more accurate than classical SEC analysis at comparable measurement times, with relative errors around 5%.
