    Far infrared studies of the formation of potassium fluoride dihydrate in and its interaction with low molecular weight polytetrafluorethylene (1981)

    Notes: Abstract The process of preparing low molecular weight polytetrafluorethylene by high temperature oxidation with potassium nitrate has been shown to lead to the formation of potassium fluoride in the polymer. This is found to absorb water vapour from the atmosphere forming its dihydrate KF.2H2O, a crystalline substance which shows a complex many line spectrum in the far infrared. The observed spectrum of KF.2H2O in the matrix differs in one major respect (the absence of a band at 73 cm−1) from that of pure KF.2H2O showing that there is some specific interaction between the dihydrate and its polymeric host.

    An independent measurement of the amorphous content of polymers (1956)
    Hoboken, NJ : Wiley-Blackwell

    Notes: Attempts have been made, particularly by American workers, to exploit differences in crystalline and amorphous polymer spectra to determine crystalline/amorphous ratios. In most published work authors have been forced to rely on calibration by other methods, especially density. They have justified the use of the spectroscopic method principally on the grounds of speed in obtaining results. We propose a spectroscopic method, applicable to a number of polymers, which is entirely independent of other measurements. We are thus able to compare our results with those obtained by other methods and have in some cases been able to draw useful conclusions from apparent anomalies. Our method depends upon measurement of pure amorphous bands. We consider these to arise from the multiplicity of rotational isomers present in the amorphous phase. The pure amorphous spectrum of many polymers can be obtained, and by this means an absolute calibration of amorphous content is possible. Crystalline bands cannot be so calibrated; they are dangerous to use quantitatively, although superficially more attractive because of their sharpness. The application of the method to some common polymers including polythene, polyethylene terephthalate, and polytetrafluorethylene is described; the results are compared with values obtained by x-ray and density methods.

    Linear polyethylene in a glassy phase: The value of the glass-transition temperature (1979)

    Notes: Raman spectroscopy, x-ray diffraction, and thermal analysis are used to investigate the structure of linear high-density polyethylene rapidly quenched from the melt to cryogenic temperatures. All the results point to the production of a glassy phase which crystallizes when heated above 170 K.

    Surface modification of extended chain polyethylene fibres to improve adhesion to epoxy and unsaturated polyester resins (1991)
    Chichester [u.a.] : Wiley-Blackwell
    Surface and Interface Analysis 17 (1991), S. 143-150

    Notes: Extended chain polyethylene fibres have been treated in ammonia and oxygen lo-pressure gas discharges (plasmas) in order to enhance adhesion to epoxy and unsaturated polyester resins, respectively, and thus significantly improve fibre/resin interfacial properties in fibre-reinforced polymer composites. Ammonia plasma treatment results in the incorporation of amine functional groups onto the fibre suface. The treated fibre surface has been analysed using XPS and spectrophotometric techniques. Extended chain polyethylene/epoxy composites made from ammonia, plasma-treated fibres show a marked increase in interlaminar shear strength over composites made from untreated, corona-treated or oxygen plasma-treated fibres. The increase in fibre/resin adhesion after ammonia plasma treatment is confirmed by SEM observations of fracture surfaces, which show clean interfacial fracture surfaces in composites made from treated fibres. Fibres modified by oxygen plasma treatment contain a significant concentration of carbon-oxygen functionalities, which contribute to the polarity of the surface and hence increase wet-out by unsaturated polyester resins. The concentration and nature of carbon-oxygen species on the fibre surface have been determined by XPS. Pull-out tests on multifilament yarns embedded in a polyester resin confirm the high fibre/matrix adhesion achieved with the oxygen plasma-treated fibres compared to corona-treated or untreated fibres. Tensile properties of the fibres are reduced significantly after prolonged treatment in an oxygen plasma, while in an ammonia plasma the fibre strength is unaffected.
