  • Abstract— Using the viscoelasticimetric tests in traction and compression mode, the viscoelastic sizes E’, E" and tand were characterized according to the temperature and this, for amorphous polymer samples differentiated by their fluidity index. It is noted that the stiffness is intermediate size making it possible to characterize the conservative components E’ easily and the dissipative one E" of the module complexes E* like its temperature of glass (vitreous) transition from polymer trough the factor of loss tand. These sizes in comparison with the abundant data by the manufacturers make it possible to consolidate the mode of request retained: The temperature of vitreous transition Tg obtained on the two samples from methylpolymethacrylate (PMMA) in modetraction compression is integrated in the interval of temperatures (110 to 135°C) advised by the manufacturers of this material. The ranks of polycarbonate (PC) tested in the two modes had a constancy of behaviour with Tg quasi equivalent to150°C with a variation of 5°C.
