“…Other techniques such as thermogravimetric analysis (TGA) can also be used to determine the composition of the polymers blends and their properties 5 , to measure the stability against temperature 14 or the thermal degradation because of the simplicity of the weight loss technique. The Fourier transform infrared spectroscopy (FTIR) has also been applied to determine the composition of polymer blends [15][16][17] since it allows to find structural changes and analyze specific bonds and interactions 18 . The thermal stability of the rubber samples has been investigated by applying TGA in combination with FTIR 19 .…”

This paper proposes an innovative approach to determine the composition of natural rubber (NR) and styrene butadiene rubber (SBR) blends from the analysis of the data provided by the differential scanning calorimetry (DSC) technique. DSC registers are post-processed, based on a multivariate chemometric approach, consisting in the application of the successive projections algorithm (SPA) as variable selection algorithm and a further application of the partial least squares (PLS) regression method and the leave-one-out cross-validation algorithm. Results attained by applying this approach are compared with those obtained from mid-infrared spectroscopy since this last method has been widely applied during the last decades. Experimental results summarized in the paper prove that this fast and cost-effective approach is useful to determine the composition of unknown incoming NR/SBR blends.

“…Much research has been recently reported on interpolymer complexes formed by hydrogen bonding when polymers containing hydrogen bond‐donating groups are mixed with polymers containing hydrogen bond‐accepting groups in a common solvent . The nature of solvent plays an important role since complex formation may result in complexes of loose or ladder‐like structures.…”

Summary Aimed to be used in very specific applications, novel materials with properties different from those of their neat constituents, based on poly(styrene‐co‐itaconic acid) (PSIA‐x) and poly(ethylacrylate‐co‐4‐vinylpyridine) (PEA4VP‐y) of various compositions, prepared by free radical polymerization, were elaborated by simply mixing pairs of these copolymers in chloroform or THF used as a common solvent. The effective specific interactions that occurred between the two constituents of the blends, evidenced by FTIR spectroscopy, depended on the blend composition and controlled the morphology of the various elaborated materials. Their phase behavior and thermal properties, investigated by differential scanning calorimetry (DSC) and thermogravimetry analysis (TGA), confirmed enhanced thermal stability of most of these materials and differences in their mechanism of degradation. Moreover, the apparent activation energies of thermal degradation of a specific blend system estimated using Tang's method also confirmed a change in the thermal behavior of these materials with blend composition.
