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

Figure 2

Scheme of the function of the magnetic coupling at deformation with a constant macroscopic shear rate (i.e., a constant angular velocity of the outer magnet). The two colors (orange and green) denote the different poles of the magnet. (a) Magnetic coupling at rest (). (b) Initial phase of shearing with continuously increasing angular velocity of the inner magnet (). (c) Steady-state condition with equal angular velocities of the inner and outer magnet ().
