- Abstract:
- We report the synthesis and characterization of well-defined homo- and diblock copolymers containing poly(furfuryl glycidyl ether) (PFGE) via living anionic ring-opening polymerization using different initiators. The obtained materials were characterized by SEC, MALDI-TOF MS, and 1H NMR spectroscopy and molar masses of up to 9400 g/mol were obtained for PFGE homopolymers. If the amphiphilic diblock copolymer PEG-block-PFGE was dissolved in water, micelles with a PFGE core and a PEG corona were formed. Hereby, the hydrophobic PFGE core domains were used for the incorporation of a suitable bismaleimide and heating to 60 °C induced the crosslinking of the micellar core via Diels-Alder chemistry. This process was further shown to be reversible.
