【摘要】 从二氧化硅与乙二醇、氢氧化钾反应生成的高反应活性的五配位硅钾化合物出发,首先以此为原料与2-氯乙醇反应制备双羟基四配位有机硅单体,然后再将其与己二酰氯进行低温溶液缩聚合成脂肪族含硅聚酯。探讨了不同反应条件对聚合物结构和性能的影响,并对合成的聚合物作了红外光谱、热重分析、分子量的测定等结构表征。更多还原

【Abstract】 A high reactive pentacoordinate organic silicon colmplex 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 was synthesized by low-temperature solution condensation between tetracoordinate silicon and adipoyl chloride. The influence of different reaction condition on structure and performance of silicon-containing polyester was studied. The product was characterized and analyzed by FT-IR, TG, GPC, etc.更多还原
