    Notes: Tetramethylene terephthalate-tetramethylene sebacate copolymers containing up to 20 mol % sebacate have been prepared and characterized. Molecular weights and distributions have been evaluated using viscometry and gel-permeation chromatography. Compositions have been established by NMR spectroscopy. Thermal properties have been studied by differential scanning calorimetry and dynamic mechanical methods. Melting and glass-transition temperatures and moduli are discussed in terms of the structural differences, particularly the effect of composition on chain flexibility. Density and thermal methods of crystallinity determination are critically discussed for these systems.

    Notes: Fibers have been prepared from tetramethylene terephthalate-tetramethylene sebacate copolymers, containing up to 20 mol % of the latter, using a conventional melt-spinning technique. The mechanical properties of these undrawn fibers and of highly oriented fibers prepared from them have been evaluated. The changes in mechanical properties brought about by the introduction of sebacate groups in poly(tetramethylene terephthalate) have been related to the glass-transition temperatures of the copolymers and to the flexible nature of the sebacate unit. The formation of voids during a continuous drawing process and during mechanical testing is discussed.

    Copolyester studies. VII. The dyeing behavior of undrawn fibers derived from tetramethylene terephthalate: Poly(tetramethylene oxide) random block copolymers (1981)

    Notes: A series of copolymers based on poly(tetramethylene terephthalate) containing poly(tetramethylene oxide) blocks whose molecular weights ranged from 1000 to 5000 in concentrations from 10 to 30% by weight was prepared. The polymers were melt spun into fibers and the undrawn fibers dyed with a disperse dye at three temperatures. The equibrium adsorption and diffusion coefficient of the dye increased with both the molecular weight and concentration of the polyether. The equilibrium adsorption varied linearly with both the molecular weight and concentration. It has been assumed that the equilibrium dye partition coefficient KM gives a parameter of the accessibility, V, of the fiber for dye. If the diffusion coefficient DM is given by DM = VDo/τ, where Do is the diffusion coefficient of the dye in the amorphous regions and τ is a tortuosity factor, a good correlation can be obtained between KM and DM, suggesting that changes in Do/τ vary in a systematic fashion.

    The accessibility of sulphonic acid groups in basic dyeable polyester fibers. I. The prevention of fiber hydrolysis during dyeing (1981)

    Notes: The rate of acid hydrolysis of a basic dyeable polyester in water, before and after heat-setting, has been investigated. Intrinsic viscosity measurements and chemical analysis have been used to establish experimental conditions under which the hydrolysis is inhibited. It is suggested that the critical stage of the hydrolysis mechanism is the exchange of sodium ions from the sulphonate groups in the fiber for hydrogen ions.

    The effect of addition of high-density polyethylene on the crystallization and mechanical properties of polypropylene and glass-fiber-reinforced polypropylene (1982)

    Notes: High-density polyethylene up to about 30% by weight was melt-mixed with polypropylene and short-glass-fiber-reinforced polypropylene. The presence of high-density polyethylene and glass fibers in the polypropylene matrix affects its crystallization characteristics, which were studied with the help of differential scanning calorimetry. The blend and composite samples have a large number of polypropylene domains apparently due to an abundance of surface nuclei; as a result, the tensile strength, tensile modulus, and toughness are enhanced. The temperature dependence of shear modulus and logarithmic decrement indicate that high-density polyethylene can have plasticizing effect below the glass transition temperature of polypropylene. The scanning electron micrographs of fractured ends show the presence of dispersed domains in the composite samples.

    Description / Table of Contents: Adhesive substances and materials of construcitonWith a view to the practical usage of adhesive substances in industry and handicraft the most essential physical and chemical powers active in the coming about of an adhesive coupling are discussed. It is found that for the achievement of the maximum effect a certain proportion between adhesion and cohesion is the preliminary condition both with the wet and the dry adherence. The adhesive powers arising with one and the same adhesive substance are dependent on the surface-nature of the construction material used, whereas the cohesive powers vary with the nature of the adhesive substance itself. Furthermore, several in special cases arising secondary powers are described which support for hamper these processes.After an enumeration and short definition of practically important types of adhesive substances and their field of usage it is examined which aspects should be decisive for the technic of processing in the plant. On the one side different construction materials can be coupled by oen and the same adhesive substance and on the other side the same fundamental type can be available in several forms ach of which is only suiable or one kind of working up.
    Notes: Unter dem Gesichtswinkel der praktischen Anwendung von Klebstoffen in Industrie und Handwerk werden die beim Zustandekommen einer Klebeverbindung wirksamen wesentlichsten physikalischen und chemischen Kräfte diskutiert. Hierbei ergibt sich, daß sowohl bei der nassen als auch bei der trockenen Haftung ein bestimmtes Größenverhältnis zwischen den Adhäsions- und Cohäsionskräften zur Erzielung der maximalen Wirkung Vorbedingung ist. Die auftretenden Adhäsionskräfte sind bei ein und demselben Klebstoff von der Oberflächenbeschaffenheit des zu verbindenden Werktoffes abhängig, während die Cohäsionskräfte mit der Art des Klebstoffes selbst wechseln. Weiter werden einige in speziellen Fällen auftretende untergeordnete Kräfte beschrieben, die diese Vorgänge unterstützen oder hemmen.Nach der Aufzählung und kurzen Definition der für die Praxis wichtigen Klebstofftypen mit ihren hauptsächlichsten Anwendungsgebieten wird untersucht, welche Gesichtspunkte für die betriebliche Verarbeitungstechnik entscheidend sind. Verschiedene Werkstoffe können einerseits durch denselben Klebstoff verbunden werden, andererseits kann der gleiche Grundtyp in mehreren Formen vorliegen, von denen jede einzelne nur für eine bestimmte Verarbeitungsart geeignet ist.
