dc.description.abstract | Tento článek srovnává odezvy objemové a entalpické relaxace v polykarbonátu pod teplotou skelného přechodu, Tg. Iniciciace relaxace byla prováděna metodou teplotního skoku pod Tg, zde materiál relaxoval a poté byl proveden teplotní skok směrem vzhůru na teplotu rovněž pod Tg. Objemová a entalpická měření byla porovnávána poměru (dh/dv) nazývaného objemový relaxační modul. Tato nová metodologie srovnání objemové a entalické relaxace poukázala na rozdíly v obou sledovaných veličinách. | cs |
dc.description.abstract | Volume and enthalpy relaxation in polycarbonate subjected to double temperature jumps in the T-g region has been analysed. It concerns both initial Tdown-jump from equilibrium above T-g to consolidation temperature below T-g and final T-up-(jump) to relaxation temperature, also below T-g. The measured H and Vdata after Tup-jump were compared with respect to aging time calculating (dH/dV) ratio denoted as aging bulk modulus, K-a. According this new methodology H and V relaxation response after Tup-jump demonstrates differences in relaxation responses. | en |
