摘要：

The phase behavior of ultrathin polymer blends was discussed. It was observed that even though the critical composition was shifted from its bulk value for films as thick as 600 nm, the thin film binodal temperatures were always within 8 K of their bulk values. It was found that in the presence of irreversibly pinned layers, the blend phase separates very close to the bulk binodal temperature. It was suggested that new theories were necessary to understand phase transitions in thin film mixtures.
