Notes:
The crystallite size distribution and lattice distortion in the [100] direction in hot-rolled high-density polyethylenes have been obtained by the analysis of the 200 x-ray line profile, using a Fourier transform technique. In the early stage of rolling (roll ratio 〈6) crystallite orientation is accompanied by breakup of crystallites due to intracrystallite slip, whereas in the heavily rolled stage (roll ratio ≧6) deformation proceeds through intercrystallite slip without degradation of crystallites. No marked change in lattice distortion can be found on hot-rolling, at least up to a roll ratio of 8. This shows that the lattice distortion in the rolled sample relaxes to the same extent as in the original lattice when the sample is processed in the crystalline relaxation (αc) region.
