Abstract

In this work, it was studied the behavior of the nonionic surfactant aqueous solutions, containing or not a hydrotropic agent, by resonance magnetic nuclear (NMR). We have studied monofunctional diblock copolymers of poly(propylene oxide-ethylene oxide) (R-PPO-PEO-OH, where R length is linear C₄) as nonionic surfactant and sodium p-toluenesulfonate (NaPTS) as hydrotropic agent. The critical micelle concentration (CMC) of the aqueous copolymer solution was obtained from ¹H-NMR. The preliminary study of the interaction between the copolymer, under the unimer and micelle forms, and the hydrotrope, in aqueous solutions, was evaluated by ¹H-NMR and ¹³C-NMR.
