Abstract

The time evolution of the interfacial area (Q) and the elastic modulus (G') in a 50/50 PS/SAN cocontinuous blends was analyzed during annealing. Two regimes of coarsening marked by different rates of growing of the characteristic length (1/Q) and by different power laws describing the decrease of G' were identified. A simplification to Doi-Ohta Theological model for small deformations was proposed and its predictions were compared to experimental results. Good agreement was observed only for blends with relatively low interfacial tension.
