SYNTHESIS AND CHARACERIZATION OF LADDER-LIKE POLYDECYLSILSESQUIOXANE

【摘要】 <正> Ladder-like polydecylsilsesquioxane （LPDS） was synthesized by a preamminolysis reaction ofdecyltrichlorosilane with ethylene diamine, followed by hydrolysis and polycondensation reaction. LPDS issoluble in a nonpolar solvent such as heptane and insoluble in a high polar solvent such as methanol. It wascharaterized by IR, ¹H-NMR, ²⁹Si-NMR, GPC and X-ray diffraction.更多还原
