Reversible thermally induced arm release from a star polymer morphology was prepared which consists of furanic functional core and maleimide functional arm which are attached or detached via Diels–Alder (DA) reversible reactions. This approach allows the reversible bonding and debonding at 35–40 °C (DA) and 90–100 °C (retro-DA). The covalent reversibility of this process consists of 7 cycles of the DA and retro-DA reactions.
