Abstract:
Provided is a method for the production of a hollow particle, which can easily produce a hollow particle having plural spaces formed inside. The method for the production of a hollow particle is a method for the production of a hollow particle having plural spaces inside thereof, which comprises dispersing an oil-phase liquid prepared by dissolving or dispersing a polymerizable monomer and an oil-soluble polymerization initiator having polymerization initiation ability for the polymerizable monomer in a hydrophobic solvent, in an aqueous medium containing a water-soluble polymerization initiator having polymerization initiation ability for the polymerizable monomer, to form an oil droplet; and applying the oil-soluble polymerization initiator and the water-soluble polymerization initiator at the same time to the polymerizable monomer, and polymerizing the polymerizable monomer, to form a shell dividing plural spaces in a particle.
