The DA-polymer is a thermoreversible polymer network formed by a DA-cross-linking reaction, between a furan rings, present on the synthesized four-functional furan compound, with the maleimide rings, present on the bi-functional maleimide compound.

The synthesis allows tuning of the mechanical properties of the DA-polymers by varying the furan spacer length, which is the chain length of the poly(propylene oxide) chain of the Jeffamine used. A series of three DA-polymers, noted DPBM-FGE-J400, -J2000 and -J4000, with diverse mechanical properties was synthesized.
