Some alkyl and aryl-containing ladder-like polyepoxysiloxanes were successfully synthesized. Differential scanning calorimetry showed that these epoxies could be cured without any curing agent. Curing occurred solely via epoxy functionality, not via the condensation reaction of the hydroxy groups located at the end of the polymer main chains. An epoxy cured with a diamine has higher thermal stability than those without curing agent or with imidazole. Due to their unique structures, these polyepoxies can be blended with common epoxy resins to increase the thermal stability of the latter.
