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、能谱元素分析等结构表征。
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 ClCH2CH2OH 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.
