摘要
(Chemical Equation Presented) 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). © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
