    Notes: Abstract During the Eocene-Oligocene, the Indian plate collided with the Kohistan arc along the Main Mantle Thrust (MMT) zone. The structure of the Lower Swat rock sequence, on the Indian plate directly south of the MMT, is a dome with a basement of granitic gneiss and quartz-rich schist unconformably overlain by amphibolitic and calcareous schist. The earliest superposed small-scale folds (F1 & F2) represent a progressive F1/F2 deformation that is associated with a single set of WSW-vergent large-scale folds (termed F2). These folds are inferred to have developed during oblique, WSW-directed overthrusting of the MMT suture complex onto the Lower Swat rock sequence. Metamorphism began during F1/F2 as indicated by an S1 foliation that developed during biotite-grade metamorphism. S1 is preserved as a relict texture in porphyroblasts that grew during a subsequent interkinematic phase during garnet- and higher grade metamorphism. The dominant, regional foliation (S2) developed following the interkinematic phase. S2 is associated with transposition of S1 and rotation or dismemberment of porphyroblasts. Annealing recrystallization followed S2 and continued during F3 thereby destroying or masking possible pre-existing stretching fabrics. Superposed F3 folds are upright and open with N-S axial trends. They may correlate with early doming of the Lower Swat rock sequence and with strike-slip displacement in the northern part of the MMT zone, north of the Lower Swat area. F3 was followed by retrograde metamorphism and development of E-W-trending, S-vergent F4 folds. F4 may be associated with a final phase of southward directed thrusting and inactivity in the MMT zone. Correlation of published 40Ar/39Ar ages with the metamorphic fabrics suggests that F1/F2 and F3 occurred in the Eocene, and that F4 developed in the Oligocene. F4 is the earliest indication of southward verging structures on this part of the Indian plate.

    Notes: This study was undertaken to measure quantitatively the flammability characteristics of cotton and polyester fibers. The smoke density generated during the burning of these fabrics was also studied at various temperature conditions. A mathematical relationship was established between the results obtained in an oxygen-depleted atmosphere chamber and those obtained in a chamber in which there was constant replenishing of an oxygen and nitrogen atmosphere. Three commercially available flame-retardant treatments were utilized in this study. The effect of temperature as well as the influence of fabric weight on the flammability behavior and the smoke density of these fabrics were investigated. A novel instrument built according to ASTM standards was employed throughout this study; it was found to be versatile, convenient, and highly reproducible in the generation of the data. It was found that polyester fabrics generate far more smoke than cotton fabrics without the phenomenon of afterglow. It was found also that as the temperature increases, the smoke density of cotton fabrics increases as well, but in the case of polyester fabrics the opposite relationship was obtained.

    Description / Table of Contents: Durch Polymerisation von Phenyl- oder n-Butylisocyanat in verschiedenen Lösungsmitteln in Gegenwart anionischer Katalysatoren wie Lithium- oder Natriumalkylen wurden kristalline Polymere erhalten.Für beide Polymere werden die IR-Spektren, die Röntgenbeugungsspektren und andere physikalische Eigenschaften wiedergegeben. Die möglichen Strukturen der beiden kristallinen Polymeren werden diskutiert. Mit kationischen Katalysatoren (z. B. AlBr3) wurden im Fall des Phenylisocyanats amorphe Polymere erhalten, während das n-Butyl-isocyanat keine Polymere lieferte.
    Notes: By polymerizing phenyl or n-butyl isocyanate in various solvents in the presence of anionic catalysts such as lithium or sodium alkyls, crystalline polymers were obtained. For both polymers, the I.R. spectra, the X-ray diffraction spectra and other physical properties are reported. The possible structures of the two crystalline polymers are discussed. By cationic catalysts (e.g. AlBr3) amorphous polymers were obtained from phenylisocyanate, but no polymers from n-butylisocyanate.

    Description / Table of Contents: Kristalline Copolymere von 3-Methylbuten mit 2,4-Dimethyl-2,7-octadien oder 2,6-Dimethyl-2,7-octadien wurden mit 28-40-proz. Umsatz hergestellt. Die bei einer Temperatur von 25°C in n-Heptan mit ZIEGLER-NATTA-Katalysatoren hergestellten Copolymeren sind in chlorierten organischen Lösungsmitteln unlöslich, besitzen scharfe kristalline Schmelzpunkte und wurden aus der Schmelze in Fasern versponnen. Die quantitative Analyse der substituierten Doppelbindung in diesen Copolymeren wurde mit Hilfe der Bromierungsreaktion und durch Messung der molaren Absorption der R′CH=CR′′R′′′-Doppelbindung im Vergleich mit 2,6-Dimethyl-2,7-octadien durchgeführt. Die chemische Struktur der Copolymeren wird mit Hilfe von Röntgendiagrammen und IR-Spektren aufgeklärt.
    Notes: Crystalline copolymers of 3-methylbutene and 2,4-dimethyl-2,7-octadiene and 2,6-dimethyl-2,7-octadiene, respectively, were obtained in yields of 28 40%. The copolymers, which were prepared in n-heptane with ZIEGLER-NATTA catalysts at 25°C. were insoluble in chlorinated organic solvents, had sharp, crystalline melting points and were melt-spun into fibers. Quantitative analysis of the substituted double bond present in these copolymers were made by the bromination reaction and by use of the molar absorptivity of the R′CH=CR′′R′′′ unsaturation using the 2,4-dimethyl-2,7-octadiene polymer as reference. The Chemical structure of these copolymers has been documented by their X-ray diagrams and infrared spectra.

    Notes: The reaction of two molecules of AlRCl2 with an electron donor molecule D, gives rise to the practically quantitative formation of AlR2Cl and AlCl3.D. This can explain the catalytic activity in the stereospecific polymerization of propylene to isotactic polymer of the systems prepared from violet TiCl3, AlRCl2, and an electron-donor substance. These systems have the same degree of stereospecificity as the systems consisting of AlR2Cl—TiCl3 (violet).
