Viscoelasticity of polymer/oligomer athermal blends

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

The viscoelastic properties of poly(α-methyl styrene), its hexamer, and their athermal blends at various concentrations are studied. Master curves for the dynamic shear responses, G' and G", are successfully constructed for both the pure materials and the blends, indicating the validity of the time-temperature superposition principle. The shift factors used to construct the master curves show weaker dependence in the blends. The segmental dynamics appear unchanged by concentration, which is different from the calorimetric studies where mixtures show obviously broadened glass transitions and depressed enthalpy overshoots.
