    Description: The types of Comatricha anastomosans Kowalski, C. filamentosa Meyl., C. suksdorfii Ellis & Everh. var. aggregata Meyl. and Lamproderma longifilum H. Neubert, Nowotny & K. Baumann were studied. Comatricha anastomosans is synonymized with C. filamentosa, C. suksdorfii var. aggregata with Symphytocarpus confluens (Cooke & Ellis) Ing & Nann.-Bremek. A new lectotype for C. filamentosa is proposed. The synonymy of L. longifilum with C. anastomosans is confirmed. SEM and light microscope micrographs of spores, capillitia and sporocarps are given.

    Description / Table of Contents: Investigations on the effect of the structure of some important anionic emulsifiers of the carboxyl, sulfat and sulfonate series on the emulsion polymerization of butadiene with styrene are described. The overall reaction rate vBr of emulsion copolymerization is differently affected by these compounds in dependence on the chain length of the alkyl or alkylaryl groups. This effect shows particularly in the stage of particle formation. Further effects on the decomposition of potassium peroxide disulfate caused by carboxyl, sulfate and sulfonate groups were found. No effect of the number of C atoms in the alkyl chain of carboxylic acid salts (C12—C18) was detected.
    Notes: Es werden Untersuchungen über den Einfluß der Struktur einiger wichtiger anionischer Emulgatoren der Carboxyl-Sulfat- und Sulfonatreihe auf die Emulsionscopolymerisation von Butadien/Styrol mitgeteilt. Die Verbindungen üben, in Abhängigkeit von der Kettenlänge ihres Alkyl- bzw. Alkylarylrestes, einen unterschiedlichen Einfluß auf die Bruttoreaktionsgeschwindigkeit vBr der Emulsionscopolymerisation aus. Dieser Einfluß zeigt sich besonders in der Teilchenbildungsperiode. Es wurden weiterhin Einflüsse auf den Kaliumperoxodisulfatzerfall in Abhängigkeit von der Carboxyl-, Sulfat- bzw. Sulfonatgruppe gefunden. Ein Einfluß der C-Atomzahl in der Alkylkette von Carbonsäuresalzen (C12—C18) war nicht zu erkennen.

    Description / Table of Contents: Polyurethanes obtained by reacting mercapto-terminated oligobutadienes, decanedithiol and diisocyanate were investigated by electron microscopy and x-ray scattering. The dependence of the morphological structure on the content of short-chain dithiol is discussed. Heterogeneities in micro- and macroregions were observed, which are caused by crystalline regions and phase separation in chemically different blocks.
    Notes: Polyurethane auf der Basis von mercapto-terminierten Oligobutadienen, Decandithiol und Diisocyanat werden mittels Elektronenmikroskopie und Röntgenstreuung untersucht. Ihre morphologischen Besonderheiten werden in Abhängigkeit vom Gehalt an Kurzkettendithiol diskutiert. Es treten Heterogenitäten im Mikro- und Makrobereich auf, die durch kristalline Bereiche und Phasentrennung in chemisch unterschiedliche Blöcke bedingt sind.
