Emulsion templated norbornadiene is cured via ring-opening metathesis polymerization 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 O2 g-1 foam. In closed volumes of air, a final oxygen level of a maximum of 0.0005 vol%, that is, 5 ppm(v) can be achieved after several hours at room temperature. The synergism of the porous morphology and the chemical nature of the polymer allows for the first example of an organic oxygen scavenger material with properties distinctly surpassing the state-of-the art in the field.

开环易位聚合制备大孔聚降冰片二烯的快速除氧。

乳液模板化的降冰片二烯通过开环易位聚合反应进行固化，产生孔隙率达76％的大孔聚（降冰片二烯）泡沫，具有吸引人的刚度和可观的延展性。在室温下，在空气存在下，泡沫很容易被氧化，表现出的氧气吸收能力超过300 mg O2 g-1泡沫。在封闭的空气中，在室温下放置数小时后，最终的氧气含量最高为0.0005 vol％，即5 ppm（v）。多孔形态和聚合物化学性质的协同作用使有机除氧剂材料的第一个例子具有明显超越了本领域的现有技术的性能。
