Abstract

Surface enrichment of one-phase and phase-separated blends of polystyrene (PS) and poly(vinyl methyl ether) (PVME) by the latter component, which has the lower surface free energy, has been examined using attenuated total reflectance infra-red spectroscopy. The apparent surface concentration of PVME, determined by assuming compositional homogeneity within the depth probed, as a function of blend composition, agrees well with data derived by other methods. Although no effect due to variations in the PS molecular weight was evident, star-shaped PS appears to behave differently from linear PS. © 1993.
