Abstract
New polyamides containing aminothiophenol, xylyl and thioetherunits were prepared under microwave irradiation and their solubility, thermal behavior, viscosity and surfacemorphologywere evaluated. 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.
