Poly(silane arylether arylacetylene) (PSEA) resins with acetylene groups at different substituted positions were synthesized and the effects of the substituted positions of acetylene groups on the properties of PSEA resins were investigated. The resins possess a wide processing window. The cured resins display high mechanical properties and thermal stability. mmm-PSEA-C possesses better mechanical properties than pmp-PSEA-C. The decomposition temperatures of pmp-PSEA-C and mmm-PSEA-C are over 530 °C.
