Summary By DSC measurements it has been determined that blends of Polycarbonate (PC) and a ABS “core-shell” terpolymer with 24 %-wt of Acrylonitrile and 6 %-wt of Butadiene seems to show limited miscibility due to the partitioning of the oligomers contained on each raw material. Like in other PC blends systems, the composition of the conjugated interphase is not constant but depends on the ratio of components in the blend. In all the compositions studied the apparent solubility of ABS (actually the SAN phase) in the PC-rich phase increase with decreasing volume fraction of PC in blends reaching a maximum at 10 %-wt of ABS. Yield Stress of the blends follows the rule of mixture almost until 10 %-wt of ABS, indicating that interfacial adhesion is strong enough to ensure stress transfer between phases in the course of yielding and drawing. Applying the Puckánszky et al. model, it was observed that over 15 % wt of ABS, the effectiveness in stress transfer depends on the morphologic gradient generated during the mixing and specimens' moulding.
