    Abstract: Disclosed are microporous, open-celled polymeric foams formed by polymerizing a high internal phase water-in-oil emulsion comprising a continuous oil phase and discontinuous water phase where the foam has a Limiting Oxygen Index (LOI) value of at least about 18 %. Such foams are commonly known in the art as 'HIPEs'. The foams have a variety of flame retardant applications, including use in insulation.

    Abstract: A process is provided for curing a high internal phase emulsion to form a porous crosslinked polymeric material, comprising the steps of: forming a high internal phase emulsion having at least one curable phase; providing a continuous strip of polymeric film wherein the polymeric film is incompatible with each of the phase of emulsion; placing at least a portion of the emulsion continuously on the polymer film; closing the polymeric film around the emulsion; spiraling the emulsion in the polymeric film onto a spool, wherein the spool rotates about an essentially vertical axis for storage of the emulsion during curing; and curing the emulsion within the polymeric film on the spool. Apparatuses to perform this process are also disclosed.
