To distinguish the different binders by SR-FTIR, we propose spectroscopic markers as the comparison of the intensity of carbonyl band around 1730-1735 cm with bands at 1160 (for acrylic), 1230 (for PVAc), and 1270 cm (for alkyds). On the other hand, oil/resin binders are characterized ...
Specific interactions between both homopolymers were studied using FTIR microspectroscopy, which allowed us to obtain spectra for both PVA-richer and PVAc-richer domains. These spectra demonstrated that partial miscibility could occur only for blends with a higher PVAc content and, in these cases, ...
Comparative measurements were carried out with minute samples using a diamond cell for transmission FTIR microscopy. The results were interpreted by comparison to database spectra measured in transmission mode. The appearance of distorted peaks in raw reflection spectra impedes a direct comparison with ...
