Popis: The interactions of egg yolk phosphatidylcholine liposomes with F108 and F127 triblock copolymers, in the monomer state, were analyzed by isothermal titration calorimetry (ITC) at 37 °C. According to the results, the critical micelle concentration was determined to be 0.4 and 0.04 wt.% for F108 and F127, respectively, by surface tension at 37 °C. According to the results, liposomes/poloxamers were not favoured energetically, since endothermic interactions were observed. However, positive changes in entropy promoted a spontaneous process. F127 had a greater partition coefficient (51.97 ± 1.77 × 10
