Polymeric catalysis: Imidazoles grafted onto poly(vinylamine). I. Synthesis and grafting of imidazolylalkanoic acids
(John Wiley & Sons, Inc., 1985-02)
Some Ω-(1-imidazolyl) and Ω-[4(5)-imidazolyl]alkanoic acids were synthesized and grafted onto poly(vinylamine) with an amide bond. These water-soluble grafts were used to study the kinetics of the esterolysis of activated ...
Nucleic acid base grafted polyethylenimine. Cytosyl pendant groups: Elucidation of structure with solution spectroscopy
(John Wiley & Sons, Inc., 1985-09)
In a previous paper, potassium 2-(cytos-1-yl)propanoate was grafted onto polyethylenimine of various molecular weights. These water-soluble polynucleotide analogs exhibited remarkable properties in their solution ultraviolet ...
Spectroscopic studies of poly( N -acyldehydroalanines) containing asymmetric nucleic acid base derivatives as pendant groups
(John Wiley & Sons, Inc., 1985-07)
Water-soluble polynucleotide analogs having a poly( N -acyldehydroalanine) {poly(Α[–( N -acylamino)acrylate])} backbone were studied by 360-HMz 1 H-NMR, UV, and CD spectroscopies. Significant UV hypochromicity values for ...
Polymeric catalysis: Imidazoles grafted onto poly(vinylamine). II. Kinetics of the esterolysis of activated phenyl esters
(John Wiley & Sons, Inc., 1985-02)
In the previous paper, some Ω-(1-imidazolyl) and Ω-[4(5)-imidazolyl]alkanoic acids were synthesized and grafted onto poly(vinylamine). These water soluble catalysts of varying apolarity contain both hydrophobic and ...
Synthesis of poly(vinyl alcohol) containing asymmetric nucleic acid base derivatives as grafted pendants
(John Wiley & Sons, Inc., 1985-05)
The preparations of new model polymers of polynucleotides with linear poly(vinyl alcohol) (PVA) backbones and an optically active nucleic acid base derivative as a pending side chain are described. (±)-, (+)-, and ...
The reaction of optically active nucleic acid base derivative with polyvinylamine in nonaqueous media: Grafting reaction
(John Wiley & Sons, Inc., 1985-06)
No Abstract.
Electron density measurements of argon surface-wave discharges
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1985-09)
The electron density of microwave-generated surface-wave discharges in argon have been measured using Stark broadening and calculated from the measured wavelengths of the standing surface wave. Results obtained from these ...
The molecular and crystal structure of pentacarbonyl(phosphabenzene)molybdenum(0)
(Elsevier, 1985-03-05)
Pentacarbonyl(phosphabenzene)molybdenum(0) crystallizes in the Pbam space group with Z = 8, a 15.880(4), b 20.162(4) and c 7.971(3) A. The crystal structure was determined and refined from 1404 independent reflections to ...
Molybdena on titania : I. Preparation and characterization by Raman and Fourier Transform Infrared spectroscopy
(Elsevier, 1985-04)
Titania-supported molybdenum and cobalt-molybdenum catalysts were prepared by the dry impregnation and equilibrium adsorption techniques. Raman and Fourier Transform Infrared spectroscopy were used to follow the changes ...
