PROBLEM TO BE SOLVED: To largely generate hollow particles in a short time without passing through a hollowing step of removing core substance.SOLUTION: In the method for producing hollow particles of forming a solid membrane at the gas-liquid boundaries of bubbles generated by blowing a gas including a monomer into a liquid, by retaining a suitable preparation environment such as the reduction of the temperature of the liquid to a room temperature or below and the reduction of its pH to 7 or lower, large and fine hollow particles are produced.COPYRIGHT: (C)2015,JPO&INPIT【課題】中空粒子を芯物質を除去する中空化工程を経ることなく短時間で多量に発生させる。【解決手段】液体中にモノマーを含む気体を吹き込んで発生させた気泡の気液界面で固体膜を形成させる中空粒子の生成方法において、前記液体の温度を室温以下に下げる、もしくはpHを7以下に下げるなど好適な調製環境を保つことにより、多量かつ微細な中空粒子を製造する。【選択図】図1
