Effect of alcohols on aqueous micellar solutions of PEO-PPO-PEO copolymers: A dynamic light scattering and 1H NMR study

► Effect of alcohols on aqueous solution behavior of three PEO-PPO-PEO block copolymers was investigated. ► The short chain alcohols favor demicellization, increase CP and CMT while higher chain alcohols show the opposite behavior. ► The DLS and viscosity results showed micelle growth for higher alcohols which remain in the palisade layer of micelles. ► The results are interpreted in terms of hydrogen bonding and hydrophobic hydration.
