TL;DR: In this paper, the authors show that the dynamic mechanical spectra in the glass transition region of miscible blends show an extraordinaryly broad transition zone when the blend has a high concentration of poly(vinylethylene).
Abstract: The dynamic mechanical spectra in the glass transition region of miscible blends show an extraordinaryly broad transition zone when the blend has a high concentration of poly(vinylethylene). The application of the coupling model to the data suggests that this breadth is a manifestation of an inhomogeneous distribution of relaxation times and coupling parameters engendered by concentration fluctuations. A consequence of this dynamical heterogeneity is deviation from the principle of time-temperature superpositioning for miscible polymer mixtures in the glass transition region

TL;DR: In this article, a blend of biodegradable polymers comprising (A) about 5 % to about 95 % by weight of at least one flexible polymers (B) having a glass transition less than about 0 °C, (C) about 0.25 to about 10 weight % of one compatibilizer (C), said percentages being based on the total weight of the polymer blend; where the polymers have a higher zero shear melt viscosity than polymers separately.
Abstract: This invention relates to a blend of biodegradable polymers comprising (A) about 5 % to about 95 % by weight of at least one flexible biodegradable polymer (A) having a glass transition less than about 0 °C, (B) about 5 % to about 95 % by weight of at least one rigid biodegradable polymer (B) having a glass transition greater than about 10 °C, and (C) about 0.25 to about 10 weight % of at least one compatibilizer (C), said percentages being based on the total weight of the polymer blend; where the polymer blend has a higher zero shear melt viscosity than polymers (A) and (B) separately.

TL;DR: In this paper, the formation of strong intermolecular hydrogen bonding was detected by FTIR analysis for softwood kraft lignin/polyethylene oxide (PEO/PEO) blends.
Abstract: Blends of poly(ethylene oxide) (PEO) with softwood kraft lignin (SKL) were prepared by thermal blending. The miscibility behavior and hydrogen bonding of the blends were investigated by differential scanning calorimetry (DSC) and Fourier transform infrared (FTIR) spectroscopy. The experimental results indicate that PEO was miscible with SKL, as shown by the existence of a single glass-transition temperature over the entire composition range by DSC. In addition, a negative polymer–polymer interaction energy density was calculated on the basis of the melting point depression of PEO. The formation of strong intermolecular hydrogen bonding was detected by FTIR analysis. A comparison of the results obtained for the SKL/PEO blend system with those previously observed for a hardwood kraft lignin/PEO system revealed the existence of stronger hydrogen bonding within the SKL/PEO blends but weaker overall intermolecular interactions between components; this suggested that more than just hydrogen bonding was involved in the determination of the blend behavior in the kraft lignin/PEO blends. © 2005 Wiley Periodicals, Inc.
