Abstract
Two novel reactive poly(β‐cyanoethylsilsesquioxane) (CN‐T) and poly[(β‐cyanoethylsilsesquioxane)‐co‐(β‐methylsilsesquioxane)] (CN‐Me‐T) have been synthesized successfully for the first time via stepwise coupling polymerization (SCP). A variety of characterization methods including FTIR, ^1^H NMR, ^29^Si NMR, X‐ray diffraction (XRD), differential scanning calorimetry (DSC) and vapor pressure osmometry (VPO) were combined to demonstrate that the structures of the title polymers possess ordered ladder‐like structures. As expected, the ionic conductivity of these polymers mixed homogeneously with lithium perchlorate reached 10^−6^ S · cm^−1^ at room temperature and obviously increased with the raise of temperature.
