    Segmental orientation studies of polyether polyurethane block copolymers with different hard segment lengths and distributions (1985)

    Notes: Abstract The orientation behavior of two series of segmented polyether polyurethanes containing different hard segment length distributions has been studied as a function of the average hard segment length which was varied from one to five methylene bis (p-phenyl isocyanate) (MDI) units. The orientation behavior of the soft segments, isolated hard segments, and of hard segments aggregated in hard domains was determined from the dichroic behavior of representative infrared bands. As the hard segment length increases, a transition in orientation behavior is observed which corresponds to a change in sample morphology. The effects of annealing and hard segment length distribution were also studied and were shown to affect the orientation response through their influence on sample morphology. Orientation hysteresis studies were performed to probe the mechanism of the transverse orientation and orientation inversion which occurred in polyurethanes with the longer, more crystallizable hard segment lengths.

    Description / Table of Contents: Zusammenfassung Die Kristallstruktur eines Skapolithes (52% Me) mit starken Überstrukturreflexen (h+k+l=ungerade) wurde in der RaumgruppeP 42/m bestimmt. Dreidimensionale Intensitätsdaten wurden auf einem Normalstrahl-Einkristall-Diffraktometer mit Zr-gefilteter Mo-Strahlung gesammelt. Das Ergebnis der vorliegenden Strukturuntersuchung bestätigt zusammen mit früheren Ergebnissen (Lin undBurley, 1973a, b) die theoretischen Schlüsse vonLin undBurley (1973c). Zwei quantitative Beziehungen bei Skapolith wurden aufgezeigt: 1. Die Exponentialbeziehung zwischen dem Intensitätsverhältnis (r) ΣI h+k+l=ungerade/ΣI h+k+l=gerade und der atomaren Verschiebung der Atome von der mit der RaumgruppeI 4/m konsistenten Spiegelebene, und 2 die lineare Beziehung zwischenr und dem Unterschied in der Al-Besetzung der Positionen T 6; 7 und T (2).
    Notes: Summary The crystal structure of a scapolite (52% Me) with strong superlattice (h+k+l=odd) reflections has been determined in the space groupP 42/n. The three-dimensional intensity data were collected with a normal beam single-crystal diffractometer using Zr-filtered Mo radiation. The result of the present structural investigation, together with two reported previously (Lin andBurley, 1973 a, b) confirms the theoretical conclusions (Lin andBurley, 1973 c). Two quantitative relationships in scapolite have also been established, (1) the exponential relationship between the intensity ratio (r) ΣI h+k+l=odd/ΣI h+k+l=even and the atomic displacement of atoms from the mirror plane consistent with the space groupI 4/m; (2) the linear relationship betweenr and the difference in the Al occupancy between T (2) and T (3) sites. The horizontal disposition of the positionally disordered CO3 groups in this scapolite is the same as in other scapolites, but the vertical disposition is different; the planar CO3 groups are tilted from the horizontal (001) plane.

    On the weak reflections violating body-centered symmetry in scapolites (1973)

    Description / Table of Contents: Zusammenfassung Röntgenbeugungs-Untersuchungen zeigen, daß die meisten Skapolithe der RaumgruppeP4 2 /n angehören. Die durchschnittliche Intensität der schwachen Reflexe, welche der Raumzentrierung widersprechen, erreicht bei 37% Meionit-Momponente ein Maximum — für die reinen Endglieder nähert sie sich dem Wert Null. Alle intermediären Skapolithe der Marialith-Meionit-Reihe sind pseudo-raumzentriert und mit Annäherung der Zusammensetzung an jene der Endglieder wird die Struktur echt raumzentriert (I4/m) Die schwachenh+k+l ungerade Reflexe stehen (1) mit Ordnung-Unordnung von Al und Si im Tetradergerüst und (2) mit strukturellen Abweichungen von der Raumzentrierung in Beziehung. Die Skapolithe können als kontinuierliche homogene Mischkristallreihe betrachtet werden. Die Zelldimensionen ändern sich nur ungefähr linear mit der Zusammensetzung; die stärkste Abweichung von der Linearität tritt bei jenen Skapolithen (25% Me bis ≈ 45% Me) auf, deren Symmetrie am stärksten von der Raumzentrierung abweicht. Diese Phänomene werden aus den strukturellen Eigenheiten der Skapolithe interpretiert.
    Notes: Summary X-ray diffraction studies reveal that most scapolites belong to space groupP4 2 /n. The mean intensity of weak reflections violating body-centered symmetry, reaches a maximum around 37 per cent meionite and extrapolates to zero at the pure end-members. All intermediate scapolites of the marialitemeionite series are pseudobody-centered, and as the composition approaches that of the end-members the structure becomes truly body-centered (I4/m). The weakh+k+l odd reflections are directly related to (1) orderdisorder of Al and Si in the tetrahedral framework and (2) structural distortion from body-centered symmetry. Scapolites may be regarded as a continuous, homogeneous solid solution. The cell dimensions are only approximately linearly related to composition and there is a maximum deviation from linearity, for those scapolites (25% Me ≈ 45% Me) whose symmetry departs the most from body-centered symmetry. These phenomena are interpreted in terms of the structural characteristic of the scapolites.

    A micromechanical study of the evolution of the yield locus of an 1100 aluminium sheet due to rolling (1998)

    Notes: Summary The purpose of the current study is to better understand the cold-rolling process through a micromechanical study. The dominant deformation mechanism is assumed to be the crystallographic slips in crystals. Specifically, the texture development in the metal sheet due to cold-rolling is simulated with a Taylor-type model, and the resultant yield loci are determined by employing Harren's self-consistent formulation to the situation in which the loading directions are not coaxial with the symmetric axes of the metal sheet. The calculations are evaluated with experimental data. Results show that these micromechanical models are quite successful in predicting the plastic behavior of metal sheets subject to moderate cold-rolling.

    Properties of UV-curable polyurethane acrylates: Effect of reactive diluent (1985)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Applied Polymer Science 30 (1985), S. 647-666

    Notes: Several families of UV-cured polyurethane acrylates were synthesized, and the effects of reactive diluent type and content on their physical properties were investigated. Increasing reactive diluent content promoted the development of a second, high glass transition temperature phase in all the materials, thereby leading to increased strength and modulus. Changes in the extensibility of the samples upon addition of reactive diluent were inversely related to the effect of the diluent on the crosslink density. The effects of using different reactive diluents (di-, tri-, and tetraethylene glycol diacrylate and N-vinyl pyrrolidone) on the physical properties of the samples were attributed to differences in the softening point (Tg) of the homopolymer reactive diluents and the relative compatibility of the reactive diluents with the urethane acrylate segments.
