多晶硅副产四氯化硅制备硅氧高聚物的研究

A Study on the Synthesis of Silic-oxide Polymers by Using the By-Product of Silicon Tetrachloride from the Preparation of Polycrystalline Silicon

利用工业生产多晶硅副产的ＳｉＣｌ４为原料与脂肪醇反应合成原硅酸酯，再经过催化水解缩合聚合，制备含硅氧链的高聚物．该高聚物用有机高分子物改性，可制得耐高温耐腐的材料．

Using Silicon tetrachlorid from a by product of the industial prepartion for polycrytalline silicon as a new material and being ted with fatty alcohol, an orthogono-silicate ester has been synthesized, and then by catalyti ti' ization and condensation polymerization a high polymer containing silic-oxide chain i;tined. After the polymer being modified by organic polymer,the high temperature and ic n resisting material can be made.
