## Abstract We have investigated the fluorescence emission spectra of pyrene and anthracene dyes covalently bonded to polystyrene (PS) upon phase separation from poly(vinyl methyl ether) (PVME). The specific chemical structure of the fluorescent labels is found to affect the measured phase separati

Polystyrene (PS) samples carrying terminal or in-chain nitroxide spin labels have been blended with poly(vinyl methyl ether) (PVME) in varying proportions and their electron spin resonance (ESR) spectra recorded over a range of temperatures. The spectra are mainly of the slow-motion type but reΓect
## Abstract The effects of phase separation temperature and time on the tensile, dynamic mechanical, and tear properties of blends of polystyrene and poly(vinyl methyl ether) were investigated after phase separation above their respective cloud points with specified temperatureβannealing time proto
The effect of phase-separated morphology on the rheological properties of polystyrene/poly(vinyl methyl ether) (PS/PVME) blend was investigated by optical microscopy (OM), light scattering (LS) method, and rheology. The blend had a lower critical solution temperature (LCST) of 112Β°C obtained by turb
