    Notes: An FTIR study has been performed on two low molecular weight model compounds of diethylmaleate functionalized polyethylene, ethyl 3-carbethoxy-4-propylheptanoate (EPH) and ethyl 3-carbethoxy-4-hexyldecanoate (EHD), recording spectra in different solvents (heptane, tetrahydrofuran, carbon tetrachloride, chloroform) and in the presence of a presumable PVC model, 2-chlorobutane (2CB). These different systems allowed the observation of some correlations between spectroscopic data and chemical composition of solutions and functionalized polyethylene/PVC blends, supporting the hypothesis of specific hydrogen bond type interactions between the carboxylic oxygen of the functionalized polyethylene and the methinic hydrogens of PVC.

    FTIR-microspectroscopy and DSC studies of poly(vinylidene fluoride) (1996)
    New York, NY [u.a.] : Wiley-Blackwell
    Polymer International 41 (1996), S. 35-41 
    Details
    ISSN: 0959-8103
    Keywords: fourier transform-infrared microspectroscopy (FTIR-M) ; DSC ; poly(vinylidene fluoride) ; polymorphism ; Chemistry ; Polymer and Materials Science

    Notes: Poly(vinylidene fluoride) (PVDF) samples, obtained by casting from tetrahydrofuran solutions and submitted to various thermal treatments, have been examined by Fourier transform-infrared microspectroscopy (FTIR-M) and differential scanning calorimetry (DSC). This kind of analysis allowed us to examine microdomains of samples with different morphological characteristics and to obtain an indication of the polymorphism of PVDF. In some cases the simultaneous presence of two or three forms has been evidenced thanks to the comparison of FTIR-M spectra and DSC traces. Vibrational spectra of single crystalline forms can be recorded by FTIR-M on phase homogeneous microdomains.
