    Irreversible effects of moisture on the epoxy matrix in glass-reinforced composites (1981)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Physics Edition 19 (1981), S. 197-212 
    Details
    ISSN: 0098-1273
    Keywords: Physics ; Polymer and Materials Science

    Topics: Chemistry and Pharmacology , Physics
    Notes: The irreversible effects of moisture exposure on anhydride-crosslinked epoxy resin films are investigated by means of Fourier-transform infrared spectra. Hydrolytic attack of water at the ester linkages is accelerated in alkaline media and is a mechanically activated process. Matrix hydrolysis is also enhanced in the presence of inorganic fillers.

    Fourier-transform infrared study of the reversible interaction of water and a crosslinked epoxy matrix (1981)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Physics Edition 19 (1981), S. 1567-1575

    Notes: Fourier-transform infrared spectroscopy is utilized to characterize the interaction of a crosslinked epoxy matrix with sorbed water vapor. The perturbations of the epoxy vibrational spectrum are evidence for weak H bonding between water molecules and polar groups in the resin. The epoxy-water interactions are reversible.

    Thermally induced conformational changes in poly(vinyl chloride) (1977)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Physics Edition 15 (1977), S. 1379-1395 
    Details

    Notes: Fourier transform infrared spectroscopy has been used for the detection of thermally induced conformational changes in atactic poly(vinyl chloride) (PVC). Difference spectra emphasize changes in the distribution of gauche defects in the chains as functions of temperature and annealing. Specific bands in the ν(CCl) and δ(CH2) regions varied with inverse temperature, allowing a calculation of the activation energies of the rotamer species. Conformational changes were also detected in quenched PVC films as a result of annealing below the glass transition temperature, Tg.

    Crosslinking mechanism of an anhydride-cured epoxy resin as studied by fourier transform infrared spectroscopy (1981)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Chemistry Edition 19 (1981), S. 549-570 
    Details
    ISSN: 0360-6376
    Keywords: Physics ; Polymer and Materials Science

    Topics: Chemistry and Pharmacology
    Notes: Fourier transform infrared spectra, including absorbance difference spectra, are presented which indicate that the accepted mechanism of tertiary amine-catalyzed copolymerization of cyclic anhydrides and epoxy resins requires modification. Results also show that the kinetic model is complicated by the lack of steady-state concentrations of the active species. The effect of silica filler and silane coupling agents on the reaction are also examined.

    Spectroscopic determination of the in-situ composition of epoxy matrices in glass fiber reinforced composites (1980)
    Brookfield, Conn. : Wiley-Blackwell
    Polymer Composites 1 (1980), S. 24-31 
    Details
    ISSN: 0272-8397
    Keywords: Chemistry ; Chemical Engineering

    Notes: Computerized infrared analysis is applied to the characterization of a glass-reinforced crosslinked polyester. The method of factor analysis determines the number of independent components which constitute the polymeric matrix. Subsequently, the spectra of those components are fitted by a least-squares criterion to spectra of the multicomponent matrix, or, if the glass spectrum is included as an additional component, to the spectra of composites. The least-squares coefficients yield the matrix composition in terms of the initial reactant composition and the extent of crosslinking.
