Abstract

A novel technique to measure enthalpy recovery in polymer glasses after carbon dioxide pressure jumps has been developed in our laboratory. Specifically, we modified a Setaram C80 Calvet differential scanning (DSC) calorimeter to work under moderate CO ₂ pressures. In the present work, we show first results for such experiments for polystyrene in which the pressure is changed from 4 MPa to 2 MPa, 1 MPa and ambient conditions.
