Morphology of the Polystyrene/Poly(Vinyl Methyl Ether) Blend as Studied by Excimer Fluorescence

Abstract

Excimer fluorescence is used to study conformational statistics and aggregation in miscible and immiscible blends of polystyrene with poly(vinyl methyl ether). At low polystyrene concentration in miscible blends, excimer fluorescence of isolated polystyrene chains is analyzed in terms of a one- dimensional random walk of the migrating singlet exciton. At high concentration in miscible blends the energy migration is three-dimensional. Knowledge of the fluorescence behavior for miscible blends is used to determine the phase composition for phase separated blends. (Author)
