Abstract

An entropically driven closed-loop phase behavior was observed for dPS-PnPMA diblock copolymers. The pressure dependence of the T_LDOT and T_UODT were found to be similar in magnitude, though opposite in sign. The magnitude of the pressure coefficients was consistent with theoretical arguments with that predicted by the Clausius-Clapeyron equation.
