NMRendgroepanalyse
NMRendgroepanalyse, often abbreviated as NREA, is a technique used in chemistry to determine the functional groups present at the end of a polymer chain. It leverages Nuclear Magnetic Resonance (NMR) spectroscopy, a powerful analytical method that probes the magnetic properties of atomic nuclei. By analyzing the chemical shifts and coupling patterns of specific nuclei, particularly protons (¹H) and carbon-13 (¹³C), information about the surrounding atomic environment can be deduced.
In NREA, the focus is on signals that are characteristic of end groups. These signals often appear
This technique is particularly useful for characterizing polymers synthesized through step-growth polymerization or polymerization mechanisms that
