The Liquid−Glass and Liquid−Liquid Transitions of TPP at Elevated Pressure

We studied the polyamorphism of the liquid triphenyl phosphite by means of broadband dielectric spectroscopy at ambient and elevated (p = 500 MPa) pressures. The effect of pressure on fragility, liquid−liquid phase transition, and its kinetics is discussed in relation to the two-order-parameter mode...

Description
Summary:We studied the polyamorphism of the liquid triphenyl phosphite by means of broadband dielectric spectroscopy at ambient and elevated (p = 500 MPa) pressures. The effect of pressure on fragility, liquid−liquid phase transition, and its kinetics is discussed in relation to the two-order-parameter model proposed by Tanaka. The experimental evidence in support of this model is presented.
