双层倍半硅氧烷与DOPO衍生物线性共聚物的合成及表征

Synthesis and Characterization of Copolymer with DDSQ and DOPO Derivative

在Karastedt催化剂作用下,双层倍半硅氧烷(DDSQ)与含双烯丙基的ODOPB(ODOPB-XM)进行硅氢加成反应,得到结构新颖的含磷硅线性共聚物,产率80%。该共聚物经~1H NMR、^(31)P NMR、^(29)Si NMR表征和凝胶色谱及热重分析,所得结果与其结构相吻合,具有良好的热稳定性。

In the presence of Karastedt catalyst, a novel linear polymer was synthesized by the hydrosilylation reaction betweendouble-decker-shaped silsesquioxane （DDSQ） and ODOPB containingtwo allyl groups with yield 80%. The copolymer was characterized by 1H NMR, 31p NMR, 29Si NMR,GPC and TGA. The specturm analytical result was consistent with compound structure, and theTGA results show that it has good thermal stability.
