Notes:
Dynamic mechanical properties of the ultrahigh molecular weight nylon 66 film and fiber produced by thermally induced solid-state polycondensation are presented. The α peak temperature of tan δ of these treated films and fibers is shifted 8-32°C higher than that of the appropriate control nylon 66 (film and fiber) while the maximum height of the tan δ peaks is decreased. The treated fibers have higher moduli at all temperatures (20-145°C) and humidities (30% RH) than do their control counterparts. The moduli of the treated fibers at 30% RH compare favorably with control yarn at 0% RH. These yarns also have a greater per cent of the 25°C modulus retention as temperature increases.
