    Conditions for polymerization-condensation and the method of reaction ofcopolymerized polyamide having a pyridine ring in the main chain have beeninvestigated. Properties of polymerized products by use of an excess or deficient of amine against the ester were first investigated and it was found that asuperior product was obtained by selecting a strictly equimolar ratio or closeto it. It was also confirmed that n-butanol can be used as a solvent but 66-Nylon salt was unsuitable as a copolymerization-condensation raw material. Acomparatively large amount of a monomer was reacted in a small spinning potand it was found that using of a peculiar method of adding water as alreadyreported in the first of this series gave a high molecular polymerized fiberfree from coloration. Using of viscosity stabilizer ameliorated vigorous foamingduring the heating in vacuo but it also effected to prevent the reaction offorming of high molecular weight, therefore, its excessive use should be avoided. A suitable amount of methanol as a solvent and the amount of water to beadded were determined. The yield of polymer was increased somewhat byfeeding a slightly larger amount of prepolymer in the reaction vessel of thesame capacity. Since the fiber having a mechanical strength 5-6g/d andelongation 20-30% can easily be made experimetally, the superiority of thiscopolymerized polyamide fiber is much anticipated.

  • Reactions of Nitro Compounds with α, α'-Azobisisobutyronitrile

    1-Cyano-1-methylethyl radicals produced by the decomposition of α, α'-azobisisobutyronitrileattacked the nitro group of nitrobenzene, m-dinitrobenzene andtetranitromethane yielding hydrogen cyanide, acetone and, in the case of thefirst two compounds, N-phenyl-and N-(m-nitrophenyl)-O, N-bis-(1-cyano-1-methylethyl) hydroxylamines. Nitromethane and ethyl nitrate did not react withthis radical. There was a rough parallelism between the amount of acetoneproduced in the present reaction and the retarder efficiency of nitro compoundsin the polymerization. Thus, it is concluded that retardation of the viny polymerizationby aromatic nitro compounds is due to formation of polymer alkoxyradicals and a nitroso compound by reaction of the nitro group with growingpolymer radicals. The nitroso compound thus formed combines with two growingpolymer radicals to yield a trisubstituted hydroxylamine.
