    Notes: Organic Electron Conductors and Precursors. V. Synthesis of Poly (organylthio-acetylenes)Poly(bis-organylthio-acetylenes) 2 and poly(mono-organylthio-acetylenes) 3 have been synthesized by complex catalyzed polymerization of the corresponding acetylenes (4 resp. 5). Yields and properties of the polymers 2, 3 depend on reaction conditions, the catalyst and the nature of the acetylenes. Relations between these influence factors are discussed.

    Notes: Iodation of N-Aryl-2,4-dimethyl-buta-1,3-dien-1,4-sultamesBy the iodation of N-aryl-2,4-dimethyl-buta-1,3-dien-1,4-sultames 1 with I2/HgO in EtOH/AcOH the 1,2-thiazine ring is substituted. The monosubstitution occurs on the 1-position (1a, d) and the disubstitution on the 1,3-position (3a). By iodine monochloride in CHCl3 the sultames 1a-d were substituted in the (C-2)-CH3 group (4a-d), in contrast also to the results of chlorination and bromination of 1. The structure of the products 2, 3, 4 was proved by 13C-n.m.r. spectroscopic data.

    Notes: Heterocyclic Substituted Arendiazonium Salts with a Long-wave-length Range of Sensitivity  -  Part I: Monomethins and AzamethinsTwo new types of arendiazonium salts have been synthesized. In these compounds a heterocycliden ring is bridged through a methine group (8a-o) or a nitrogen (11a-c) with the 4-position of a benzene diazonium group.Both types show sensitivity towards normal day-light, their long wave-length absorption band vary from 430 nm up to 590 nm, depending on the donor strength of the heterocycliden ring and the nature of the bridging group.The thermostability, the quantum yields of photochemical dediazonation and the coupling behaviour of the diazonium salts are investigated, in order to evaluate their potential applicability in a commercial diazotype system.

    Description / Table of Contents: The fractions of the supermolecular structure with respect to a three-phase model were estimated by Raman spectroscopic investigations on different polyethylenes. The temperature dependence of the structure parameters is discussed. The results are compared with crystallinity values from desity, infrared, WAXS and NMR measurements.
    Notes: Für verschiedene Polyethylene werden ramanspektroskopisch die Anteile der übermolekularen Struktur nach einem Dreiphasenmodell bestimmt, und deren Temperaturabhängigkeit wird diskutiert. Die Ergebnisse werden mit Kristalliniatätswerten aus Dichte-, Infraot-, Röntgenweitwinkel- und NMR-Messungen verglichen.

    Description / Table of Contents: Die von Strobl und Hagedorn angegebene Methode zur ramanspektroskopischen Charakterisierung der Polyethylenstruktur wurde auf gereckte Proben unterschiedlicher Trübung angewandt. Die Abhängigkeiten der Masseanteile der orthorhombisch-kristallinen, der amorphen und der Zwischenphase vom Reckverhältnis werden diskutiert.
    Notes: The method described by Strobl and Hagedorn for analysing the structure of polyethylene by means of Raman spectroscopy has been applied to drawn samples of different turbidity. The dependence of the mass fractions of the orthorhombic crystalline, the amorphous, and the intermediate phases on the draw ratio is discussed.
