| 摘 要： | 利用二元羧酸二叔丁基酯和氯硅烷缩聚合成聚硅基酯的方法合成了聚(己二酸-1,1,5,5-四甲基-3,3-二苯基-三硅氧烷硅基酯)和聚(己二酸-四甲基二硅氧烷硅基酯)2种新型可降解聚硅基酯.利用核磁共振氢谱(1H NMR)、核磁共振碳谱(13C NMR)、红外(IR)表征了聚合物的结构,利用热失重分析(TGA)、示差扫描量热分析(DSC)、凝胶渗透色谱(GPC)对聚合物的性质进行了表征.

| Abstract: | The two degradable poly(silyl ester)s included poly(1,1,5,5-tetramethyl-3,3-diphenyl-trisi1oxyl adipate) and poly(tetramethyldisilyloxyl adipate) were synthesized by a new route via the condensation of di-tert-butyl ester of dicarboxylic acid with dichlorosilane.The chemical structures of the poly(silyl ester)s were confirmed by 1H NMR,13C NMR and IR spectroscopies.The properties of the poly(silyl ester)s were researched by thermogravimetry analysis(TGA),differential scanning calorimetry(DSC) and gel permea... |
