An amino group on the s-triazine ring has a character like that of an amino group in an amide group because of the electron-attracting effect of the s-triazine ring. It does not react with carboxylic acid chloride a t low temperatures.'s Consequently, we prepared diamines that contained the amino group directly attached to an aromatic nucleus which is connected with the s-triazine ring by groups that carry lone-pair electrons like oxygen and an -NHgroup able to contribute electrons. We synthesized the aromatic diamines I, 11, IV, and VI (Table I) represented by the following structure: Ph IThe diamines that contained -NHbridges were prepared by reacting rn-@-)phenylene-diamine with 2,4-dichlor-6-phenyl-s-triazine. The diamines that contained -0-bridges were obtained from the corresponding dinitro compounds by reduction with h e y Ni and hydrogen in an autoclave under high pressure. The dinitro compounds were synthesized from sodium m-(p-)nitrophenolate and 2,4-dichlor-6-phenyl-s-triazine. The characteristic properties and elemental analyses of these compounds are listed in Table I. The diacyl chlorides used were 4-chloroformyl-N-(rn -/p-chloroformylpheny1)phtalimides A and B, respectively*O:

The temperature dependence of the electrical conductivity and the Seebeck coefficient for some chelate-modified polysulfones (PSF-Cs) derived from chloro-terminated polysulfones and bis (2,4-dihydroxybenzaldehyde) Cu2' were studied. The measurements were performed using the thin films deposited from solution. The investigated polymers have semiconducting properties. The correlations between these properties and the molecular structure of the respective polymers are discussed.
