Emulsion templated norbornadiene is cured via ROMP yielding macroporous poly(norbornadiene)foams of 76% porosity exhibiting appealing stiffness combined with considerable ductility. The foams are readily oxidized in the presence of air at room temperature exhibiting an oxygen uptake capacity of more than 300 mg O<sub>2</sub>/g foam. In closed volumes of air a final oxygen level of a maximum of 5 ppm can be achieved after several hours at room temperature. The synergism of the porous morphology
