Synthesis of Water - soluble Polymer with Sodium Dodecyl Sulfate(cas 151-21-3) Study by 1H NMR

A series solutions of sodium dodecyl sulfate(cas 151-21-3) in the presence of 2 g / L polyvinylpyrrolidone (PVP) and 2 g /L polyvinyl alcohol (PVA) were studied by ~ 1H NMR. Two-dimensional NOESY experiments showed that SDS formed micelles at a concentration of 2.5 mmol / L and PVP was solubilized into the micelles. When SDS concentration was less than 2.5 mmol / L, there was no significant interaction between PVP and SDS. The results of the spin-spin relaxation time support this conclusion. The interaction between PVA and sodium dodecyl sulfate(cas 151-21-3) was not detected in the experiment.
