    A carbazole-based polymeric azodye (1981)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Chemistry Edition 19 (1981), S. 3155-3164 
    Details
    ISSN: 0360-6376
    Keywords: Physics ; Polymer and Materials Science
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: A new polymeric azodye has been synthesized from carbazole by diazotization of its derivative N-methylcarbazole-3,6-diamine and subsequent coupling reaction with 2,2-bis(4-hydroxyphenyl-3-sulfonate-Na)-propane prepared from bisphenol-A. Its physico-chemical, electrical, and thermal properties have been characterized; finally, its application to the preparation of colored semiconductive films from polyvinyl alcohol has been studied.

    Studies of carbazole-based polyarylates (1981)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Chemistry Edition 19 (1981), S. 2017-2026 
    Details
    ISSN: 0360-6376
    Keywords: Physics ; Polymer and Materials Science

    Topics: Chemistry and Pharmacology
    Notes: A low temperature solution condensation method with pyridine as acceptor-catalytic reagent was applied to the synthesis of polyarylates from carbazole and bisphenol A/phenolphthalein. The polyarylates were classified with respect to their structure, thermal stability, and dielectric behavior.

    Diethylzinc/metal salt initiator systems. I. Stereospecific polymerization of N-vinylcarbazole by ZnEt2/CoCl2-quinoline (1981)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Chemistry Edition 19 (1981), S. 3081-3092 
    Details
    ISSN: 0360-6376
    Keywords: Physics ; Polymer and Materials Science

    Topics: Chemistry and Pharmacology
    Notes: In the presence of ZnEt2 the CoCl2-quinoline complex polymerizes NVC with a rate increasing with ZnEt2 and CoCl2-Q concentrations up to a certain concentration of ZnEt2 or CoCl2-Q, thereafter becoming independent of either. At a fixed concentration of ZnEt2 and CoCl2-Q the rate is second order with respect to NVC. The poly(NVC) obtained is freely soluble in benzene but leaves some insoluble fraction in methyl ethyl ketone, which has been characterized by 13C-NMR to be a stereoblock polymer. X-ray diffraction, IR, and thermal characteristics of the polymer have also been reported. [η] is virtually independent of monomer, in the concentration range 0.1-0.25 mol/L ZnEt2 and CoCl2-Q concentrations. Oxygen as an additive inhibits the polymerization. A cationic coordination mechanism has been proposed and appropriate rate and degree of polymerization equations have been suggested.

    Photocrosslinking and thermal behavior of the polyesters containing conjugated diacetylenes (1981)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Chemistry Edition 19 (1981), S. 1155-1166 
    Details
    ISSN: 0360-6376
    Keywords: Physics ; Polymer and Materials Science
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: A series of polyesters containing conjugated diacetylenic groups in the polymer backbone were synthesized by interfacial condensation of 3,5-hexadiyne-1,6-diol and diacid chlorides of succinic, glutaric, adipic, azealic, sebacic, terephthalic, and isophthalic acids. The polyesters were characterized by their infrared and ultraviolet absorption spectra, elemental analysis, and viscosity measurements. Powder x-ray patterns indicated high degress of crystallinity. The polyesters were found to be highly photoreactive. The relative photoreactivities of the polyester films were determined by the adhesion method. Only small differences in the reactivity have been observed despite structural changes in the R group in the polymer backbone. Differential thermal analysis behavior of all polymers in the temperature range ambient to 300°C and isothermal behavior of HGI at two different temperatures have been studied.

    Carbon-13 NMR spectral studies on some labdane diterpenoids (1981)
    Chichester : Wiley-Blackwell
    Organic Magnetic Resonance 16 (1981), S. 75-77 
    Details
    ISSN: 0030-4921
    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: Carbon-13 NMR signal assignments of the labdane diterpenoids andrographolide and 14-deoxyandrographolide, along with their acetates, and isodeoxyandrographolide have been made. This study indicates that the C-6 and C-11 resonance assignments of isovirescenol-B, made earlier, should be interchanged.

    Notes: Carbon-13 signal assignments of the labdane diterpenoids phlogantholide-A, its diacetate and isophlogantholide-A are reported. The assignments of the 13C NMR signals of 14-deoxyandrographolide and its diacetate, made earlier, have now been confirmed by lanthanide shift studies on the former and also by 13C spectral studies on anhydroandrographolide diacetate and 14-deoxy-11,12-didehydroandrographolide diacetate.
