    Abstract: High internal phase emulsions (HIPEs) and polyHIPEs formed therefrom. HIPE components have been adjusted to delay and/or prevent polymerization and free radical decomposition at certain temperatures. Methods include preparing two water-in-oil emulsions; one emulsion includes an oxidizing initiator at a concentration not sufficient to induce polymerization, and another emulsion includes a reducing agent. The two emulsions may be stored for months. When combined, a redox reaction is induced, resulting in polymerization (polyHIPE formation) at temperatures below 100°C, such as between 20°C and 40°C. This allows a final composition to be formed in situ, with or without highly sensitive materials, including biologically-derived or active constituents (e.g., cells, growth factors, enzymes, proteins, drugs, chemoactive agents). The polymerization rate may be short, as fast as thirty seconds. HIPE components as well as the redox reaction may be controlled to manipulate time to cure, pore size, distribution of pores, and/or internal contents.

    Abstract: According to the present invention, there is provided a porous polymer material and a method of production thereof, where a large majority, for example 80 % or more, or even up to about 100 % of the material is in the form of substantially spherical beads with narrow bead size distributions. These polymeric beads have a porous structure, characterized by cavities joined by interconnecting pores (a HIPE structure), some of which are connected to the surface of the bead.

    Abstract: The invention relates to foam composites having improved properties. These polymeric foams are prepared by polymerization of certain water-in-oil emulsions having a relatively high ratio of water phase to oil phase, commonly known in the art as high internal phase emulsions, or "HIPEs." The HIPE-derived foam materials used in the present invention comprise a generally hydrophobic, flexible, semi-flexible, or rigid nonionic polymeric foam structure of interconnected open-cells. These foam structures have a density of less than about 100 mg/cc, a glass transition temperature (Tg) of between about -40 DEG and 90 DEG C, and at least about 1 % by weight compatible fibers incorporated into the foam. The foam composites have improved tensile properties compared to foams having no incorporated fibers or foams having noncompatible fibers incorporated therein.
