초록

계면활성제 sodium dodecyl benzene sulfonate (SDBS)가 흡착되어 있는 CaCO3를 제조하고 methyl methacrylate (MMA)를 단량체로, ammonium persulfate를 개시제로 사용하여 core(내부)와 shell(외부)의 성분이 다른 무기/유기 core-shell polymer를 합성하였다. 무기/유기 core-shell polymer 제조에서 SDBS를 2.0 wt% 첨가하여 제조한 CaCO3를 core로 하여 MMA를 shell 중합한 것이 CaCO3 입자 표면에서 polymethyl methacylate (PMMA) shell 중합이 잘 유도되었으며 중합 도중 새로운 PMMA 입자의 생성이 적음을 알 수 있었다. 이와 같은 방법으로 합성된 polymer composite의 전환율과, CaCO3 분해에 따르는 HCI 소비량, thermogravimetric analyzer를 이용한 열분해 중량감소, differential scanning calorimeter를 이용하여 유리전이온도의 측정, scanning electron microscope 촬영에 의한 morphology와 입자의 분산 형태를 관찰하여 core-shell 구조를 확인하였다.

CaCO3 which adsorbed sodium dodecyl benzene sulfonate (SDBS) surfactant, was prepared. Core-shell polymers of inorganic/organic pair, which have both core and shell components, were synthesized by a sequential emulsion polymerization using methyl methacrylate (MMA) as the shell monomer and ammonium persulfate as the initiator. We found that when CaCO3 core was prepared by adding 2.0 wt% of SDBS, CaCO3/MMA core-shell polymerization occurred readily on the surface of CaCO3 particle without forming significant amount of new PMMA particles. The structure of core-shell polymer was investigated by measuring the degree of decomposition of CaCO3 using HCl solution; thermal decomposition of polymer composite using thermogravimetric analyzer; glass transition temperature by differential scanning calorimeter; and morphology by scanning electron microscope.

Keywords:core-shell;inorganic/organic;CaCO3;methyl methacrylate
