Synthesis of Y-shaped poly(solketal acrylate)-containing block copolymers and study on the thermoresponsive behavior for micellar aggregates

► The thermoresponsive polymeric micelles from Y-shaped polymers MPEG-block-(PSA)2. ► The micelle sizes were decreased with temperature increasing. ► Nile red release from the micelles occurred at 37 °C rather than 25 °C.
