    Description / Table of Contents: Formstoffe aus aromatischen Polyepoxiden, aromatischen Polyaminen mit hochtemperaturbeständigen Strukturelementen sowie pulverförmigen Füllstoffen besitzen hervorragende Eigenschaften, wie hohe Glasübergangstemperatur, hohemechanische Festigkeit, kleinen thermischen Ausdehnungskoeffizienten und Schwerbrennbarkeit ohne Zugabe von Flammschutzmitteln. Über die Synthese dieser aromatischen Polyamine, die Herstellung und Verarbeitung der Niederdruckpreßmassen sowie die Eigenschaften der Formstoffe wird berichtet.
    Notes: Moulded materials produced from aromatic epoxide resins, aromatic polyamines with high-temperature-resistant structure units and powdered mineral fillers possess outstanding properties like high glass transition temperatures, high mechanical strength, low linear thermal expansion coefficient, and reduced flammability without the addition of flame retardants. An account is given of the synthesis of aromatic polyamines, the preparation and working of moulding materials and the properties of the finished products.

    Poly(p-benzamide). II. Thermal behavior and crystal transformations (1986)
    Bognor Regis [u.a.] : Wiley-Blackwell
    Journal of Polymer Science Part B: Polymer Physics 24 (1986), S. 1675-1682 
    Details
    ISSN: 0887-6266
    Keywords: Chemistry ; Polymer and Materials Science

    Topics: Chemistry and Pharmacology , Physics
    Notes: The thermal behavior and crystal transformation of poly(p-benzamide) are reported. Modification I contains both solvent (N,N-dimethylacetamide) and LiCl in its crystal lattice. Modification II is likely to form a complex crystal with LiCl, whereas crystalline modification III contains neither solvent nor LiCl in its unit cell. The crystal transformation temperature from modification I to II is 214°C, and the crystal-nematic transition temperatures of modification II and III are 475 and 544°C, respectively. Modification III can be obtained from II by heating above 475°C and cooling, or by washing with water. It can also be obtained from modification I by washing with water and annealing.

    Poly(p-benzamide): Magnetic field orientation, solvation, and crystal-crystal transformations (1986)
    Bognor Regis [u.a.] : Wiley-Blackwell
    Journal of Polymer Science Part B: Polymer Physics 24 (1986), S. 1115-1119 
    Details
    ISSN: 0887-6266
    Keywords: Chemistry ; Polymer and Materials Science

    Topics: Chemistry and Pharmacology , Physics
    Notes: The morphological features of poly(p-benzamide) films cast in a magnetic field from solutions in N,N-dimethylacetamide containing LiCl are reported. Three crystal modifications are found, one solvated and the other two containing no solvent. The solvated crystal grown in a magnetic field is oriented with the molecules parallel to the field. It transforms to an oriented amorphous phase by loss of solvent, and this conversion is accelerated by the presence of moisture. Upon annealing at an elevated temperature, the crystalline solvate transforms to a second crystal form, while the amorphous sample is converted to a third crystalline modification. All three crystalline forms have almost the same fiber identity period, which corresponds to a nearly fully extended chain conformation.

    Reactionss of Sodium Hydrazide with Organic Compounds (1964)
    Weinheim : Wiley-Blackwell
    Angewandte Chemie International Edition in English 3 (1964), S. 342-353 
    Details
    ISSN: 0570-0833
    Keywords: Sodium hydrazide ; Chemistry ; General Chemistry
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: The reactions of sodium hydrazide with organic compounds are reviewed for the first time. The great variety of these reactions is mainly due to the extraordinary ease with which the hydrazide ion adds onto unsaturated compounds, usually to form unstable adducts that achieve stability in various ways.
