Abstract: Thermoplastic aromatic polyether-pyridines are composed of repeating structural units each containing one or more pyridine rings. These polymers are prepared by a polycondensation reaction between a 2,6-dihalogenopyridine and one or two dihydroxy compounds, or between a bis(6-chloro-2-pyridyloxy) compound and a dihydroxy compound, the reactions being performed substantially in the absence of water. The degree of polymerization may be 10 or greater. The polymers have an excellent combination of heat resistance, moldability and other properties, and hence are useful in a wide variety of applications.

Abstract: A crude 3,3'-dinitrodiphenyl compound selected from 3,3'-dinitrodiphenylsulfone or 3,3'-dinitrobenzophenone is purified by reacting the crude 3,3'-dinitrodiphenyl compound with a lower alcohol in the presence of a base so as to convert practically the isomer or isomers, which contain one or more nitro groups at the ortho- or/and para-positions, only into the corresponding alkoxy compound or compounds thereof and then separating the alkoxy compound or compounds.

Abstract: BIS (3-AMINOPIIENOXY) AROMATICS AND METHOD OF PREPARING THE SAME Bis(3-nitrophenoxy) derivatives of aromatic or bridged aromatic hydrocarbons are derived from m-dinitrobenzene and dihydroxy derivatives of said hydrocarbons by a condensation reaction in dipolar aprotic solvents in the presence of bases. The bis(3-nitro-phenoxy) derivatives obtained are successively reduced to afford bis (3-aminophenoxy)derivatives. This is a new method for reacting the dihydroxy-derivatives with m-dinitrobenzene, and hence can prepare novel bis(3-aminophenoxy) derivatives such as 4,4'-bis(3-amino-phenoxy)biphenyl, 1-¢4-(3-aminophenoxy)phenyl!-1,3,3-trimethyl-6- (3-aminophenoxy)indan, 6,6'-bis(3-aminophenoxy)-3,3,3',3'-tetra-methyl-1,1'spirobiindan, and methyl substituted 2,2'-bis¢4-(3-amino-pllenoxy)phenyl!propane.
