The application of the Diels-Alder reaction to polymer syntheses based on furan/maleimide reversible couplings

Polímeros, 2005
The furan heterocycle is a dienic reagent particularly suitable for the Diels-Alder reaction and maleimides represent a typical family of complementary reagents because of their strong dienophilic character.
