Abstract

We measured the dynamic viscoelastic behavior of poly(methylmethacrylate) (PMMA)/polystyrene(PS)(8:2) blend melts.The volume average radius of droplets of dispersed phase was estimated from transmission electron microscopy(TEM) micrographs of the blend. We determined the interfacial tension by comparison of the dynamic data with the Palierne theory. The interfacial tension thus determined agrees fairly well with the values obtained by other methods.
