Experimentally, the formulation results revealed significant differences in solubilizing capacities of all triblock copolymer at varying LAP feed. The A-pPentOx-A gave maximum solubility of 5.5 g/L at 6 g/L feed (LC ≈ 35 wt.% and LE ≈ 91%) (Figure ). The further increase in the LAP feed did not improve the solubility, and it remain between 5 and 6 g/L. The similar behaviour was observed for A-pBuOx-A and A-pBuOzi-A, however the maximum achievable soluble LAP was 3.4 and 2.8 g/L, respectively. The A-pPrOzi-A was found to be least efficient in solubilizing LAP (≈ 1.5 g/L). The obtained formulation results are not in correspondence with the estimated compatibility profile.
