US Patent No: 9814656

Porous resin particles, method of manufacturing porous resin particles, and use of porous resin particles

---

Abstract

---

Disclosed are porous resin particles which contain a polymer of a monomer mixture containing, as monomers, at least a monofunctional (meth)acrylic acid ester and a crosslinking monomer. The monofunctional (meth)acrylic acid ester accounts for 1 wt % to 50 wt % of the monomer mixture, and the crosslinking monomer accounts for 50 wt % to 99 wt % of the monomer mixture. The porous resin particles have a specific surface area of 190 m²/g to 300 m²/g and a bulk specific gravity of 0.25 g/mL to 0.45 g/mL.
