Abstract We have analyzed the deformation behavior of compatible and incompatible polystyrene (PS) and poly(vinyl methyl ether) (PVME) blends by a combination of mechanical and vibrational spectroscopy. Macroscopic properties and segmental orientation were found to be sensitive to molecular weight, strain rate, and temperature of measurement above the glass‐transition temperature. Considerably different orientation functions were found for the PS and PVME components. For the experiments carried out above the T g of the blends, the deformation behavior measured was consistent with expectations of a rubbery network.
