Thermal analysis techniques are used to study the properties of polymers, blends and composites and to determine the kinetic parameters of their stability and degradation processes.Here the property of a sample is continuously measured as the sample is programmed through a predetermined temperature profile. Among the most common techniques are thermogravimetry (TG) and differential scanning calorimetry (DSC). Dynamic mechanical analysis (DMA) and dielectric spectroscopy are essentially extensions of thermal analysis that can reveal more subtle transitions with temperature as they affect the complex modulus or the dielectric function of the material. [Pg.296]

Dielectric analysis can also be used to study nanoconfinement effects in the polymer chains contained in a polymer blend. Here, the most reasonable... [Pg.575]

Electronic impedance spectroscopy (EIS) is used to measure the polymer dielectric properties and the changes in these properties with exposure time. This is based on the interaction of an external field with the electric dipole moment of the sample, often expressed by permittivity. Dielectric thermal analysis (DETA) measures the permittivity, capacitance and dielectric loss of a polymer sample under an oscillating electric field as a function of temperature. The dielectric properties of a blend system in general depend on structure, crystallinity, morphology and additives. " ... [Pg.298]

The molecular mobility and microphase separation in blends of crosslinked polyurethane (PUR) and styrene-acrylonitrile (SAN) copolymer were investigated. The PUR and SAN copolymer were prepared by reactive blending with polymer polyols. DSC, thermally stimulated depolarisation currents (TSDC) techniques, dielectric relaxation spectroscopy (DRS) and dynamic mechanical thermal analysis over a wide range of... [Pg.71]
