The viscosities of polyamides are in the range of 0.39-0.49 and glass transition temperatures (Tg) are in the range of 245-276°C. Decomposition temperatures of 10%weight loss T (10) are in the range of 133-274 °C, also, the temperature of 50% weight loss T (50) are in the range of 291-318 °C and char yields are in the range of 5-17% at 540 °C. These polyamides showed good solubility in common organic solvents. Surface morphology of these polymers showed amorphous andmicrosphere structure.
