| 제목 | Suspension polymerization of thermally expandable microspheres using high Tg initator |
| 초록 | Thermally expandable microspheres with core-shell structure have a lot of industrial application. The microspheres which have the typical diameter of 5 – 50 µm can be expanded to microballoons with 50 - 100 times larger volume. But previous monomer has a disadvantage that it has a low glass transition temperature and is difficult to expand at high temperatures. In this study, thermally expandable microspheres are synthesized with acrylonitrile(AN) and cyclohexyl methacrylate(CMA). CMA is monomer that has high glass transition temperature. So we expected core-shell is expanded on high temperature. Iso-octane and N-octane is used the blowing agent. Suspension polymerization of AN and CMA initiated by Azobisisobutyronitrile(AIBN). Butanedioldimethacrylate(BDDMA) is used as crosslinker. PVP, Silica, MgOH2 are used as the Stabilizer. Characterization is used by SEM, TGA, Coulter Acknowledgments This work was supported by a grant (1415140208/10045051) Korea Ministry of Trade, Industry and Energy (MOTIE), Republic of Korea (2015) |
