摘要
研究了直接从无定型二氧化硅出发 ,与乙二醇、氢氧化钾反应 ,生成高反应活性的五配位硅钾化合物 ,并以此为原料与 2 -氯乙醇反应制备双羟基四配位有机硅单体 ,然后该单体再与对苯二甲酰氯进行低温溶液缩聚反应合成含硅聚酯 ,并对合成的物质作了红外光谱、热重分析、分子量测定。
A high reactive pentacoordinate organic silicon complex has been prepared, by means of the reaction of silica with ethylene glycol and potassium hydroxide. Then a novel tetracoordinate silicon has been synthesized by the reaction of ClCH 2CH 2OH with reactive pentacoordinate silicon complex. Then silicon containing polyester is synthesized by low temperature solution condensation between tetracoordinate silicon and P phthaloyl chloride. The product has been characterized and analyzed by FT IR, TG, EPS, GPC etc.
