Available in PDF, EPUB and Kindle. Book excerpt: Noncrystalline thermooxidatively stable aromatic p olyamides were synthesized through the triphenyl phosphite-promoted polycondensations of 3,3-(sulfonylbis(1,4-phenylenoxy)) dibenzoic acid and 3,3(carbonylbis(1,4-phenylenoxy)) dibenzoic acid with 3,3-(1,3-phenylendioxy)dianiline. Alternatively, the polymers could be prepared through the low temperature polydensations in N-methylpyrollidone of the corresponding diacid chlorides with the aromatic diamine. An additional polyamide was synthesized through the self-condensation of 3-(4-(3-aminophenoxybenzoyl)phenoxy) benzoic acid. This previously unreported monomer had been prepared by a two-step reaction sequence from 4,4-difluorobenzophenone. Inherent viscosities in the range of 0.27-0.63 dl/g (N, N-dimethylacetamide, 30C, 0.2 g/d1) were obtained. Polymer structures were established by elemental analyses and infrared spectroscopy. Thermal characterization was carried out by differential scanning colorimetry, thermal gravimetric analysis, and isothermal aging. Keywords: Aromatic polyamide, Thermooxidative stability, Low glass transition temperature. (jes).

Book excerpt: The translation discusses the effect of lithium chloride concentration and monomeric concentration on the molecular weight of poly-n-phenylene-terephthalamide synthesized in the dimethyl acetamidelithium chloride system. It was shown that the sharp increase in the viscosity of the polymer in a domain of determined concentrations of lithium chloride was caused by the increase in the dissolving power of the solvent.
