    Notizen: Quantitative and qualitative IR analysis of some synthesized aromatic homo polysulfides and copolysulfides based on 4,4-oxydibenzenethiol (IV), 4,4-dimercaptodiphenyl sulfide (I) and bis-(4-fluorophenyl) Sulfone (II) in 1-methyl-2-pyrrolidone (NMP) has been done. A satisfactory agreement of experimental results with theory was observed.

    Synthesis, characterization, and kinetic study on the thermal decomposition of polyamidoethers (1989)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Applied Polymer Science 37 (1989), S. 1559-1565 
    Details
    ISSN: 0021-8995
    Schlagwort(e): Chemistry ; Polymer and Materials Science
    Quelle: Wiley InterScience Backfile Collection 1832-2000
    Thema: Chemie und Pharmazie , Maschinenbau , Physik
    Notizen: Some new polyamidoethers have been synthesized by condensation reaction of N,N'-dichloroacetyl-1,4-phenylene-diamine with bisphenols (4,4'-isopropylidenediphenol, 4,4'-dihydroxydiphenyl sulfone, 4,4'-dihydroxydiphenyl sulfide, and 4,4'-dihydroxybiphenyl) in N-methylpyrrolidone medium using DB-24-Crown-8 as a phase-transfer catalyst. The structure of these polymers has been characterized by infrared (i.r.) and 1H nuclear magnetic resonance (NMR) spectroscopy. Kinetic method of thermal decomposition of these polymers and their 2% mixture with polyvinylchloride (PVC) has been studied.

    The properties of some poly(arylene ether sulfones) (1980)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Applied Polymer Science 25 (1980), S. 821-828 
    Details
    ISSN: 0021-8995
    Schlagwort(e): Chemistry ; Polymer and Materials Science

    Thema: Chemie und Pharmazie , Maschinenbau , Physik
    Notizen: Some 2,4′-substituted poly(arylene ether sulfones) have been prepared and their properties compared with those of the conventional 4,4′ homopolymer. The introduction of the comonomer leads to a small increase in yield stress and to a greater tendency to brittle fracture, which can be demonstrated from fracture surface micrographs.

    Synthesis of Uridine with Methylene-2-thiohydantoin as 5-Substituent (1994)
    Weinheim : Wiley-Blackwell
    Liebigs Annalen 1994 (1994), S. 619-621 
    Details
    ISSN: 0170-2041
    Schlagwort(e): Uridine, methylene-2-thiohydantoin derivative ; Nucleosides ; 2-Thiohydantoin ; Herpes simplex virus ; Chemistry ; Organic Chemistry

    Thema: Chemie und Pharmazie
    Notizen: 5-Formyl-1-(2,3,5-tri-O-acetyl-β-D-ribofuranosyl)uracil (4) was synthesized from 5-formyluracil (2) and 1,2,3,5-tetra-O-acetyl-β-D-ribofuranose (3) and condensed with 2-thiohydantoin derivatives 5 by using piperidine as the catalyst to give 5-(uridin-5-ylmethylene)-2-thiohydantoin (8a) and 3-phenyl-5-(uridin-5-ylmethylene)-2-thiohydantoin (8b) after deprotection with sodium methoxide in methanol. Compound 8a was also obtained in an inversed reaction sequence from 5-formyluracil starting with condensation with 2-thiohydantoin and then with 3. The compounds 8a and 8b did not show any activity against HSV-1 or HIV-1.
