Abstract: | Cloud points data on solutions of a poly(ethylene oxide)–poly(propylene oxide)–poly(ethylene oxide) (PEO–PPO–PEO) abbreviated as EPE or Pluronics, such as P–65, P–84, P–85, P-105, L-64, and their mixtures at different salt (NaCl) concentrations in water are reported. The addition of NaCl to these mixed copolymers decreases cloud point, increases surface activity, and shifts micellization to lower concentration. In presence of NaCl, more surfactant is needed for demicellization of P105 micelles. |
