T h e mechanical relaxations of isotropic and oriented linear low-density polyethylene have been studied between -180 and 90ยฐC by the use of a torsion pendulum (1 Hz), a dynamic tensile apparatus (5-90 Hz), and a longitudinal wave attenuation technique (10 MHz). The five independent elastic moduli o
