SYNTHESIS AND CHARACERIZATION OF LADDER-LIKE POLYDECYLSILSESQUIOXANE*

Received Date: 25 September 1997

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.
