Abstract
Official abstract text for this publication.
A method of producing, in a liquid, a hollow particulate material having a cavity therein, the method including: (A) blowing gas into a resin solution containing a first dispersion medium; (B) pouring the resin solution to which the gas is blown in step (A) into a second dispersion medium to form liquid droplets encapsulating the gas and prepare a dispersion of the liquid droplets; and (C) solidifying the liquid droplets formed in step (B) and isolating the solidified liquid droplets from the second dispersion medium.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of producing, in a liquid, a hollow particulate material having a cavity therein, the method comprising: (A) blowing gas into a resin solution containing a first dispersion medium; (B) pouring the resin solution to which the gas is blown in step (A) into a second dispersion medium to form liquid droplets encapsulating the gas and prepare a dispersion of the liquid droplets; and (C) solidifying the liquid droplets formed in step (B) and isolating the solidified liquid droplets from the second dispersion medium. 2 . The method according to claim 1 , wherein the first dispersion medium includes an organic solvent or a polymerizable monomer. 3 . The method according to claim 1 , wherein the resin solution contains a lipophilic surfactant. 4 . The method according to claim 1 , wherein the second dispersion medium includes an aqueous solvent. 5 . The method according to claim 1 , wherein the dispersion of the liquid droplets contains an aqueous surfactant. 6 . The method according to claim 1 , wherein the resin solution has a viscosity of 10 mPa·s or more at 25° C. 7 . The method according to claim 1 , wherein the liquid droplets are solidified through removal of the first dispersion medium. 8 . The method according to claim 1 , wherein the liquid droplets are solidified through polymerization of the liquid droplets. 9 . The method according to claim 1 further comprising, between steps (B) and (C), a step of dividing the liquid droplets encapsulating the gas.
