Deformation Behavior of Extruded Blown Film of High Density Polyethylene (STATES AND STRUCTURES-Polymer Condensed States)

摘要

Deformation behavior of extruded blown film of polyetylene, which contains oriented lamellae normal to the extruded direction (MD), is investigated by scanning electron microscope and X-ray scattering techniques. Type of structural change in deformation process strongly depends on angle between stretching direction and MD. A structural model is proposed to explain the experimental results systematically.
