Influence of Carbon Dioxide on the Glass Transition of Styrenic and Vinyl Pyridine Polymers: Comparison of Calorimetric, Creep, and Rheological Experiments

Figure 9

Time-dependent tensile creep compliance of polystyrene PS 158 K at various temperatures and pressures. (a) Tensile creep compliance at a pressure of 1 bar and temperatures of 30, 50, and 70°C. (b) Mastercurve of the data in (a). (c) Creep compliance at a temperature of 30°C and pressures of 1 and 50 bar as well as the mastercurve for a pressure of 1 bar. (d) Creep compliance at a temperature of 50°C and pressures of 1, 30, and 50 bar as well as the mastercurve for a pressure of 1 bar. In (c) and (d), the data of the mastercurves appear in black color.
