Non-linear PEG-based thermoresponsive polymer systems

Poly(ethylene glycol) (PEG) is one of the most used polymers in medical and biological applications. Its non-toxicity, non-immunogenicity, biocompatibility and solubility in a wide range of solvents offer various possibilities of utilization and explain the amount of studies dealing with this polymer. More recently, non-linear PEG-based monomers attracted much interest due to their thermal behavior. The present review aims at presenting many PEG-based thermoresponsive systems from structural and synthesis point of view and at highlighting all their fascinating properties from their behavior in solution, the fine-tuning of the transition temperature until the formation of smart materials.
