摘要：

The dynamic mechanical properties of poly(hexamethylene isophthalamide) and poly(dodecamethylene terephthalamide) have been determined over a wide range of temperature at low frequencies (∼ 1 c/s) by torsion pendulum measurements and at high frequencies (∼ 500 c/s) by a vibrating reed technique. It has been shown that absorbed moisture leads to the appearance of an intermediate loss peak at temperatures in the range -20°C to -70°C, between the main glass/rubber transition at 120°C and a low temperature process with a peak near -150°C. Unlike other polyamides such as nylon 6-6, the main glass/rubber transition is unaffected by moisture. © 1969.
