Abstract: A ladder-like polysilsesquioxane (PSSQ) has been synthesized by reacting pyromellitic acid anhydride (PMDA) with (3-aminopropyl)triethoxysilane (APTES), yielding the corresponding poly(amic acid) (PAA). The as-prepared PAA was converted to an imide-functionalized PSSQ by thermal treatment at… read more here.
