Stereocomplexed PEG-PLA Hydrogels

  • Chapter
Hydrogels

Abstract

In this paper we give an overview of our studies on stereocomplexed hydrogels upon mixing aqueous solutions of enantiomeric linear poly (ethylene glycol)-poly(L-lactide) triblock (PEG-PLA) copolymers and eight-arm (PEG-PLA) star block copolymers and methacrylate functionalized PEG-PLA star block copolymers [1–3]. Stereocomplexation and photopolymerization were combined and enhanced the stability of the hydrogels. For all polymers, the critical gel concentrations of the mixed enantiomer solutions were considerably lower compared to polymer solutions containing only the single enantiomer. The gel-sol transition temperatures were increased and gel regions were expanded due to stereocomplexation.
