페닐기를 도입한 실리콘 고분자의 합성 및 물성
Synthesis and Characterization of Phenyl Modified Silicone Polymer
초록
내한, 내열성이 우수한 실리콘 고분자를 합성하기 위하여 페닐기를 도입한 1,1-diphenyl-1-methyl-7-hydroxydodecamethylheptasiloxysilane을 합성하고 이의 물성을 연구하였다. 100∼800℃의 범위에서 TGA 분석을 시행한 결과 일반 polydimethylsiloxane에 비해 열적성질이 우수하였으며, -50∼-10℃ 범위에서 내한성을 측정한 결과 유동성을 유지하였다. 또한 실리콘 고무에 합성한 실리콘 고분자를 첨가한 결과 기계적 성질이 향상되었다.
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∼800℃, the phenyl modified silicone polymer had good thermal properties than polydimethylsiloxane. And furthermore fluidity was maintained even below 0 ℃. Also, the silicone rubber blended with the phenyl modified silicone polymer had better mechanical properties than the silicone rubber.
