Abstract
In order to use vesicle as a space of polymerization, monomer and cross-linking agent were put into hydrophobic part of vesicle. The vesicle solution of dimethyl-dioctadecylammonium bromide was formed by ultrasonication. Styrene and divinylbenzene were put into this solution and polymerization was conducted by adding AIBN. The polymer with sphere-shaped structure was obtained by removing all of the surfactant by extraction of ethanol And using methyl methacrylate and ethylene glycol dimethacrylate, this sphere-shaped polymer structure was also formed.

Vesicle을 단량체가 중합 반응을 할 수 있는 장소로 사용하기 위하여, vesicle 내의 소수성 부분에 단량체와 가교제를 집어넣었다. 즉 dimethyldioctadecylammonium bromide를 증류수 속에서 초음파 분산을 하여 vesicle을 만든 후, 여기에 styrene과 divinylbenzene을 첨가한 다음 AIBN으로 중합시켰다. 형성된 고분자는 남겨두고 vesicle을 형성하였던 계면활성제들을 모두 에탄올로 추출해서 제거하여 순수 고분자로 이루어진 구형의 구조물을 얻었다. 그리고 methyl methacrylate와 ethylene glycol dimethacrylate을 이용해서도 고분자로 이루어진 구형의 구조물을 합성하였다.
