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: A method of manufacturing porous core-shell polymer particles having a nonporous shell including: providing a first organic solvent containing a dissolved polymer; dispersing the organic solvent in an aqueous phase containing a stabilizer to form an emulsion; adding the emulsion to a second organic solvent wherein the second organic solvent is miscible with water and the first organic solvent, and a non-solvent for the polymer; and evaporating the first and second organic solvents from the emulsion to form core-shell polymer particles. The method results in core-shell polymer particles comprising a common binder polymer for the core and the shell wherein the core has a porosity and the shell is non-porous. The particles have a porosity from 10 to 70 percent.
