The application relates to a process for the preparation of a microporous, open-celled polymeric foam material by polymerizing a high internal phase emulsion, which has relatively small amount of continuous oil phase and relatively greater amount of a discontinuous aqueous phase. The present application relates to use of monomer compositions having short curing times for preparing such foam materials from the emulsion, while achieving the required physical properties of the foam.

La présente invention concerne des matériaux en mousse polymère à alvéoles ouverts, microporeux, flexible, présentant des caractéristiques physiques les rendant adaptés à une variété d'utilisations. La présente invention concerne en particulier des compositions monomères présentant des temps de cuisson réduits destinés à la préparation desdits matériaux en mousse à partir d'émulsions à phase dispersée élevée.
