A quantitative study was undertaken of the anisotropy of low-strain mechanical behavior for specially oriented polyethylene with controlled crystalline and lamellar orientation. The samples were prepared by the die drawing of injection-molded rods of polyethylene and annealing. This produced a paral

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
Shear, isothermal and non-isothermal elongational data have been collected for a wide range of linear low density polyethylenes with different structures. In particular the samples differ both in molecular weight and in the comonomer. All the data show that the rheological behaviour is strongly affe
