Zusammenfassung:This paper deals with the compatibility of a chlorine-containing polycarbonate with poly(methyl methacrylate) (PMMA). The polymer-polymer interaction parameter, χ, has been determined from the experimental phase diagram by means of the Flory-Huggins theory. The interfacial tension, interfacial thickness and interfacial density profile have also been calculated from the experimental value of χ by means of Helfand's mean-field treatment. The calculated interfacial thickness has been compared to experimental data from optical, transmission and scanning electron microscopy.
