In the end: Alkyl end groups can induce a thermoreversible sol–gel transition in an otherwise sol-like suspension by affecting the macroscopic self-assembly behavior. The picture shows PLGA-PEG-PLGA triblock copolymer/water mixtures in the sol (polymer a), gel (polymers b and c), and precipitation states (polymer d). PLGA=poly(lactic acid-co-glycolic acid), PEG=poly(ethylene glycol).
