a b s t r a c t Two aromatic tetraketones, 4,4 0 -thiobis[(p-phenyleneoxy)benzil] (STK, 1) and 4,4 0 -thiobis[(p-phenylenesulfanyl)benzil] (3STK, 2) were synthesized by the nitro nucleophilic substituent reactions of 4-nitrobenzil and corresponding diol compounds. The two tetraketones were polymeriz
