    Description / Table of Contents: Aus einem phenolischen Copolymeren bekannter Zusammensetzung und verschiedenen nicht ionischen Homopolymeren (PVP, PEO, PVA) sowie Polyelektrolyten wie PAA und PEI wurden in Lösung Mehrkomponenten-Interpolymerkomplexe hergestellt. Die Bildung dieser Komplexe wurde mit verschiedenen Methoden, wie Viskosimetrie, Potentiometrie, Konduktometrie und IR-Spektroskopie untersucht. Es wird ein Schema zur Erklärung der Art der Wechselwirkung zwischen den verschiedenen Polymerkomponenten vorgeschlagen.
    Notes: Multicomponent interpolymer complexes have been prepared by interacting a phenolic copolymer of known composition with several non-ionic homopolymers, e.g., PVP, PEO, PVA and polyelectrolytes, such as PAA and PEI. The formation of these complexes has been studied by several techniques, such as viscometry, potentiometry, conductometry, and IR spectra. A scheme has been presented to explain the mode of interaction of the various component polymers.

    Description / Table of Contents: Poly(methacrylsäure-co-methacrylamid) und Poly(acrylsäure-co-acrylamid) wurden hergestellt und mit bekannten Methoden charakterisiert. Die jeweiligen Comonomereinheiten der beiden Copolymeren können durch Wasserstoffbrückenbindung und Ion-Dipol-Wechselwirkungen Komplexe bilden. Die nicht-komplexierten Einheiten der Intercopolymerkomplexe können noch entweder mit anderen Homopolymeren wie Poly(N-vinylpyrrolidon) oder Poly(oxyethylen) wechselwirken oder mit Übergangsmetallionen drei- und vierkomponentige Komplexe bilden. Die Bildung solcher Komplexe wurde mittels Viskosimetrie, Konduktometrie, Potentiometrie und IR- und UV-Spektroskopie untersucht.
    Notes: Poly(methacrylic acid-co-methacrylamide) and poly(acrylic acid-co-acrylamide) have been synthesized and characterized by known methods. The respective comonomer units of the two copolymers enter into complex formation through hydrogen bonding and ion-dipole interactions. The unreacted units in the intercopolymer complex also interact with homopolymers such as poly(N-vinylpyrrolidone) and poly(oxyethylene) as well as transition metal ions to form three and four component intermacromolecular complexes. Formation of these complexes could be shown through several experimental techniques, e.g. viscometry, conductometry, potentiometry, IR and UV spectrophotometry.

    Notes: Fired clay membranes were prepared from montmorillonite clay and also by incorporating protein (lysozyme) and nylon (copolymer of 6-amino caproic acid) to clay followed by firing these membranes at different temperatures for different durations of time. Osmotic behaviors of the membranes were studied, and the results were correlated to the porosity determined by scanning electron microscope. Reverse osmosis parameters, namely, the reflection coefficient, solute permeability, and rejection coefficient, of the membranes were determined from osmosis experiments. Rejection coefficients as determined from reverse osmosis were compared with those obtained from osmosis experiments.

    Notes: Sorption characteristics of vapors of pure hydrocarbon and their binary mixtures in low-density polyethylene were studied under various conditions of temperature and pressure. A new apparatus devised and utilized for the determination of composition of sorbed vapor in case of binary mixtures is described. The study demonstrates the effect of the presence of one component within the polymer on the sorption of another and also the occurrence of selectivity in sorption.

    Photoinduced charge transfer at the poly(N-vinylcarbazole) - tin oxide interface (1975)

    Notes: An investigation of steady state and transient photoconductivity in films of poly-(N-vinylcarbazole) equipped with SnO2 and metal electrodes is described. The studies have shown that photoinduced charge transfer, leading to hole injection into the polymer film, takes place with photons of energy greater than 1.8-1.9 eV. Dark conductivity studies on samples equipped with grounded guard rings have shown that carriers originating in the bulk of the polymer film dominate the dark current when the metal electrode is at negative bias. Thermionic hole emission from the SnO2 electrode is not observed.

    Notes: The piezoelectric coefficients (d31) for a number of bovine and human scleral collagen samples were determined as a function of drying time at room temperature. The measured values of d31 decreased with drying time. There were significant differences in the values of the d-coefficient between the human and bovine eyes as well as in the values obtained from different regions of the eye. © 1998 John Wiley & Sons, Inc.
