Emulsion-templated porous materials have gained extensively in applications due to their low density and high porosity. However, by far most this type porous polymers are synthesized using conventional radical polymerization and most of the reactions are thermally initiated. Expanding the polymerization mechanisms available for emulsion-templated polymers synthesis is still highly desired. In this work, Diel-Alder (DA) reaction was used to synthesize emulsion-templated macroporous

... ne (PCL). These macroporous polymers were prepared by DA reaction of polycaprolactone pendant with multiple furan group (PCL-furan) and 1,6-bis(maleimide)hexane (BisM) via a high internal 1 phase emulsion as template. The porous materials have a typical structure of emulsion-templated 2 materials.
