The use of a surfactant derived from the degradation of natural rubber gloves via cross-metathesis with methyl acrylate and subsequent saponification of the ester group for the stabilization of water in dicyclopentadiene high internal phase emulsions is described. The versatility of the resulting high internal phase emulsion is demonstrated by polymerizing the continuous dicyclopentadiene phase via ring-opening metathesis polymerization yielding macroporous poly(dicyclopentadiene) foams with a porosity of 82%. The use of the ionic surfactant allows for the preparation of foams, which are resistant to absorb water. This property is hitherto not accessible with protocols involving the use of nonionic surfactants commonly employed in emulsion templating of polymers.

一种用于聚（双环戊二烯）高内相乳液模板化的天然橡胶废料衍生表面活性剂

描述了使用源自天然橡胶手套降解的表面活性剂，通过与丙烯酸甲酯的交叉复分解和随后的酯基皂化来稳定双环戊二烯高内相乳液中的水。所得高内相乳液的多功能性通过开环复分解聚合连续双环戊二烯相聚合得到孔隙率为 82% 的大孔聚（双环戊二烯）泡沫来证明。离子表面活性剂的使用允许制备耐吸水的泡沫。迄今为止，这种特性是无法通过涉及使用常用于聚合物乳液模板的非离子表面活性剂的方案获得的。
