Static SIMS study of miscible blends of polystyrene and poly(vinyl methyl ether)

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 constituents. A semi‐quantitative analysis of SSIMS intensities to obtain surface compositions gives good qualitative agreement with previous x‐ray photoelectron spectroscopy (XPS) results.
