## Abstract Static secondary ion mass spectroscopy (SSIMS) is applied to study the surface of the miscible polystyrene (PS)/poly(vinyl methyl ether) (PVME) blend. The blend surface is enriched with PVME and the enrichment is shown to depend on the composition and molecular weight of the blend const
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
