Abstract
The phenyl modified silicone polymer, 1,1-diphenyl-1-methyl-7-hydroxydodecamethylheptasiloxysilane, was synthesized to prepare the silicone polymer with good cold-proof and heart-proof properties. From the TGA analysis in the range of $100{\sim}800^{\circ}C$, the phenyl modified silicone polymer had good thermal properties than polydimethylsiloxane. And furthermore fluidity was maintained even below $0^{\circ}C$. Also, the silicone rubber blended with the phenyl modified silicone polymer had better mechanical properties than the silicone rubber.
내한, 내열성이 우수한 실리콘 고분자를 합성하기 위하여 페닐기를 도입한 1,1-diphenyl-1-methyl-7-hydroxydodecamethylheptasiloxysilane을 합성하고 이의 물성을 연구하였다. $100{\sim}800^{\circ}C$의 범위에서 TGA 분석을 시행한 결과 일반 polydimethylsiloxane에 비해 열적성질이 우수하였으며, $-50{\sim}-10^{\circ}C$ 범위에서 내한성을 측정한 결과 유동성을 유지하였다. 또한 실리콘 고무에 합성한 실리콘 고분자를 첨가한 결과 기계적 성질이 향상되었다.
