계면활성제 Sodium Dioctyl Sulfosuccinate (EU-DO133L)을 사용한 이산화규소/ 스티렌의 코어-셀 고분자의 합성

Synthesis on the Core-Shell Polymer of Silicone Dioxide/Styrene Using Sodium Dioctyl Sulfosuccinate (EU-DO133L) as a Surfactant

Core-Shell polymers of silicone dioxide-styrene system were prepared by sequential emulsion polymerization. In inorganic/organic Core-Shell composite particle polymerization, silicone dioxide adsorbed by surfactant sodium dioctyl sulfosuccinate (EU-DO133L) was prepared initially and then core silicone dioxide was encapsulated emulsion by sequential emulsion polymerization using styrene at the addition of potassium persulfate (KPS) as an initiator. We found that SiO2 core shell of SiO2/styrene structure was formed when polymerization of styrene was conducted on the surface of SiO2 particles, and the concentration sodium dioctyl sulfosuccinate (EU-DO133L) was 0.5∼2.0g. The structure of core-shell polymer were investigated by measuring to the thermal decomposition of polymer composite using thermogravimetric analyzer and morphology of latex by scanning electron microscope(SEM).
