| 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 ClCH_2CH_2OH 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. |
