It concerns two ways of physical aging initiation, temperature down-jump and cooling. Samples were heated and v(T) dependency measured after annealing at various aging times bellow Tg Relaxed volume was evaluated from peaks of (T) dependencies, derivated from v(T) curves. Good agreement between isothermal relaxation measurements and relaxed volume from heating has been found out. Presence of filler particles in composite lead to reduction of relaxation response and rate of relaxation changes in PMMA.
