APPLICATION OF TIME-TEMPERATURE SUPERPOSITION PRINCIPLE TO EVALUATION OF SCATTERING INTENSITY EVOLUTION IN PHASE SEPARATION FOR PMMA/SAN BLENDS
Spinodal phase separation behavior of poly(methyl methacrylate)/poly(styrene-co-acrylonitrile)(PMMA/SAN)blends was investigated by the time-resolved small angle light scattering (SALS) technique. It was found that the influence oftemperature on the scattering intensity evolution followed the time-temperature superposition principle. The relationshipbetween temperature and the relaxation time of scattering intensity I(t) can be well described by the Williams-Landel-Ferry(WLF) function.
