...The substance to be encapsulated is made to coexist in this system, and the substance is taken up in the microphase with the higher concentration and precipitated, resulting in microcapsules encapsulating the substance. (2) Interfacial polymerization This method utilizes the fact that when raw materials that react with each other to produce a polymer are dissolved in each of two immiscible solvents, a reaction occurs at the interface between the two solvents to produce a polymer. If the substance to be encapsulated is made to coexist in such a system and reacted while being vigorously stirred, the substance is taken up as the polymer is produced at the microinterface created by the stirring, resulting in microcapsules. ... *Some of the terms used in the term "interfacial polymerization method" are listed below.

…包みこむ物質をこの系に共存させ,濃度の高いほうの微小相にとりこませ沈殿させることによって,その物質を内包したマイクロカプセルを得る。(2)界面重合法 互いに混合しない2種の溶媒のそれぞれに,互いに反応して高分子を生成するような原料を溶かすと両溶媒の界面で反応が起こって高分子が生成することを利用するもの。内包させる物質をこのような系に共存させてはげしくかきまぜながら反応させると,かきまぜによって生じた微小な界面で高分子が生成する際,その物質がとりこまれてマイクロカプセルが得られる。… ※「界面重合法」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
