W/O EMULSION, FOAM, AND FUNCTIONAL FOAM |
摘要 |
Provided is a W/O emulsion, including a continuous oil phase component and an aqueous phase component immiscible with the continuous oil phase component, in which: the continuous oil phase component includes a hydrophilic polyurethane-based polymer and an ethylenically unsaturated monomer; the hydrophilic polyurethane-based polymer includes a polyoxyethylene polyoxypropylene unit derived from polyoxyethylene polyoxypropylene glycol; and the polyoxyethylene polyoxypropylene unit includes 5 wt% to 25 wt% of polyoxyethylene. Also provided is a foam, including a hydrophilic polyurethane-based polymer, in which: the foam has an open-cell structure in which through-holes are present between adjacent spherical cells; the spherical cells each have an average pore diameter of less than 20 µm; the through-holes each have an average pore diameter of 5 µm or less; and the foam has surface openings each having an average pore diameter of 20 µm or less in a surface thereof. |
